As far as I know the resolution of a film is limited to the size of the individual grains that make up the photosensitive material. Although tiny, it is limited.
I believe Sergey's camera was automated to take the 3 exposure in quick succession, with the glass photographic plates and filters automatically sliding into place between exposures. Hence minimal color fringing of live subjects.
They are impressive in every aspect. Not only it was a technological and logistical challenge with amazing results, the photos taken were also invaluable documents of a lost time. They all were taken in the last years of the russian empire before 1917, when everything changed, especially for the former russian empire. They are vivid documents of a time period long gone, buildings gone, cultures gone, even lots of the depicted activities not performed anymore for centuries now. I think this makes them even more fascinating.
soriac I was thinking the same thing when I was looking at the architecture. And remembering my history about the last Czar of the Russian Empire..but I only seen black and white pics of that era.
It ought to be mentioned that they came out only in the past decade, because they required extensive post-production (in other words, PhotoShop) in order to look as good as they do. But yes, somebody still had to take them, and they are gorgeous.

For even more fun, take a b/w photo, then move the camera a few inches to the side (still pointing at the original target) and then take another. Then composite the two photos with red for one side and green for the other and you'll get a 3D stereogram.
He would have been using either medium format or sheet film, which is multiple hundred times larger than any digital sensor in a phone camera, so the quality blows them out of the water
Bolling Holt agreed, I've only heard of him once before in a history of color photography video, but I had no clue he took that many photos, the only thing that gives away the fact they weren't taken yesterday are the clothes lmao
This really isn't a workaround, it is the basis of how each and every color image ever created is conceived. But yes I agree, using this old B&W security camera to compile a color picture is a fun innovative way of demonstrating how capturing color images works!
That's how the Hubble telescope works, too; astronomers take this concept further by creating composites in visible light AND ultraviolet, often the source images are obtained by different observatories.
What's amazing is that all of the indoor photos you captured look *exactly* like photos from the 70's and 80's. It's a super awesome way to get a natural "vintage" look to pictures with digital techniques.
The Russian chemist mentioned in the video here was commissioned by the Czar to use this technique of color photography to document life in Imperial Russia. The photos are really high quality and include landscapes and portraits across all of Russia at the time. I would highly recommend a search for the gallery of these that were put online several years ago.
Haha! The portraits with much fringing almost became anaglyph stereoscopic 3D! Just tested it with some red/cyan glasses I had on my desk! The girl do pop out from the background
Well, the subjects from Sergey didn't really need to stant completely still, because Sergey used a "camera" or projector that took 3 shots at the same time, because of that he was able to "record" relative slow moving objects but not fast moving objects, the same problem we have today.
Many CCD and some CMOS cameras used for astronomical imaging use this technique because monochrome sensors are typically more sensitive. Putting a Bayer matrix over the sensor to get color in one shot means that to reach the same amount of signal requires a longer exposure and some interpolation is required. Using a filter wheel in front of the sensor means each pixel gets access to each color, and also means you can use specialty filters that only allows certain specific wavelengths through.
That's correct but I just want to point out that all sensors are 'mono' in that it only senses a photon hitting it. And it has no idea about frequency (colour) of it. Hence the need to add filters (including bayer) to reproduce colour. Normally there is also an IR filter (astro photography excepted) added as well, to keep colour reproduction more accurate.
I was a kid in 1969 when the first color TV pictures from space were sent from Apollo 10. czcams.com/video/KbGHIQvObN0/video.html They used a color wheel, I remember Walter explaining it. They also converted it to broadcast color with a camera aimed at a screen at Mission Control. Occasionally some white space debris would fly through the view and appear as sequential red, green, and blue dots.
Monochrome cameras are also used in astronomy due to the higher resolution given. All pixels are one colour over 2* or more images, rather than a mix of red/green/blue in the one image. Essentially, a Bayer filter divides a sensor into 3, so an 18 megapixel sensor is really only capturing 6 megapixels per colour. A monochrome sensor using individual filters, 18 megapixels are captured per colour. *Sometimes, only 2 colours are used for astronomical images. Consisting of one red exposure and one blue exposure. The red and blue can then be combined to create or extrapolate the green image..
This is the principle as when taking astrophotos with non-RGB sensors. Just to make it a bit harder for you, Red, Green and Blue don't have the same focal point due to its wavelength.
I'm reminded of a very early attempt at color TV by using a color wheel in front of a B/W TV, and an identical wheel in front of the B/W camera. As it spun, the TV would display the red, green and blue images alternately and the color wheel would show them in the correct color. Due to persistence of vision, you'd see a full color image. It was a good idea in theory, but in practice keeping the wheels in sync between the camera and the TV screen proved next to impossible; not to mention the horrible flickering effect!
Tomsonic41 It wasn’t just an attempt. CBS made history’s first color broadcast using this format. That was 1950, nine years after system ‘M’ was adopted. The market chose to abandon the color wheel system for its lack of backwards compatibility, not its flickering. I’ve seen one demonstrated though, and the color artifacts are not distracting. It’s actually quite crisp.
The Apollo Moon missions sent color video back from the Moon using a version of this method. The color video cameras of the time were far too massive and bulky to take on a spacecraft, but there were B/W video cameras that were relatively compact, and they used the color-wheel method to get video separations and combined them using a lot of analog video wizardry Earthside. (If I recall correctly, part of the process literally involved correcting for Doppler shift by adjusting the slack in a strip of videotape.)
yes a lot of DLP projectors used color wheels, I can't stand them because I can actually see the color tearing sometimes... this isn't a problem with 3DLP projectors since they use a trichro like the 3CCD cameras referred to in the video
I just knew this would showcase Prokudin-Gorsky's work. The people photos he took are impressive when you think about taking 3 exposures in a row with really slow chemistry. The filters slowed his exposure even more.
It’s true, but Prokudin-Gorsky took advantage of using silver bromide based negatives, they were more sensitive to light, which helped to decrease exposure time a bit. It definitely wasn’t fast, but considering that he needed to take 3 shots each time, it helped quite a lot.
The term colourblind is a misnomer, as it doesn't mean we can't see those colours, it just means certain colours are confusing, and we can't always see the differences.
Aha ok, but you say you can't see the difference between some colors, that means you do not see the right color, so then the word colorblind is the right work no?
I wouldn't say it's a misnomer. Monochromacy (only seeing greys) exists, it's just very rare. Most people who are color blind can still see color, but the colors they can see are limited, so they are blind to those colors, at least.
B&W shot through color filters is how the color vector graphics you see in TRON were created (when Flynn has been digitized and is flying down to the Game Grid). Robert Abel & Associates created those images on the Evans & Sutherland Picture System, which was a 3D workstation built for tasks like CAD and flight simulation. It uses a B&W vectorscope display. RAA photographed these images directly off the monitor with the use of RGB filtration, shooting a pass, rolling the film back and shooting the next color record. It was time consuming but it worked and created a very specific aesthetic that's difficult to reproduce with modern motion graphics.
In 1950 CBS labs invented a color television system that used the same "sequential color" system, with a color wheel spinning in front of the image sensor on the camera, as well as a larger filter spinning in front of the display CRT. The system failed because it was not compatible with existing B&W TV's. The system was modified and updated by Westinghouse and used during the Apollo program to allow live color pictures from the Moon, as well as live color close up pictures of the launch from a camera mounted on the launch tower. To make standard broadcast NTSC color first an arrangement like the CBS system was used with a color wheel on the converter camera and on the display tube, then by Apollo 14 RCA had developed a digital system that used (non imaging) CCD's and RAM to store the frames of video then combine them digitally. Color fringing will always be a problem with sequential color systems since each frame is taken at a different time and the subject may be in a different position.

Here are the first Color TV pictures from space using the Westinghouse camera with the sequential color wheel. You can see it at 10:00. czcams.com/video/KbGHIQvObN0/video.html
These old photographs fascinate me. Then I called my brother to look at them and guess the age of the photo, and he was totally wrong, and wide-opened his eyes in surprise when I told him these are over 100 years old.
Carpoolparty Old TV shows shot on analog color cameras had this look. Lots of ‘70s sitcoms and dramas, especially. The fringing wasn’t this bad, though.
its also really easy to replicate the effect in post with photoshop or some other photo editing software, always good to give an image that extra retro flair haha.
If you want to, you can easily replicate the effect with a regular colour camera. The red, blue and green channels of a colour image can easily be separated by Gimp and then you can combine the channels from different pictures just like in this video.
6:15 is such an interesting picture. The subject came out great, it's got that grainy 70's home video look (the shorts help even more!), and the filter flares occur in a way that really adds to the picture. Very nice.
Thank you for mentioning Sergey Prokudin-Gorsky-although you pronounced his name not quite correctly ;) I admire this guy and his work ever since I’ve seen his photographs the first time many years ago. Btw: Most of his work you can find online today was digitally composed from the original black-and-white parts. Back in the days, such a perfect and flawless composition of all three components was not possible.
Color images from satellites like Himawari are composed exactly this way. The multi spectral cameras use multiple filters for red, green, blue and many near and far infrared wavelengths. If they combine the 3 color channels were get a color image from the earth.
Almost all telescopes, both Earth-based and the ones in space, use monochrome sensors + filter wheels. It's the way it has always been done, and probably the way it will always be done. Monochrome image sensors are just superior in many ways. It's also easier to create very high-quality filters that are external, and you can put them in a filter wheel to have dozens of filters available, that can automatically be rotated around as required by the telescope.
This is how we used to get color scans from a black-and-white flatbed scanner back in the day. Nobody had a color scanner in the eighties, when they probably cost almost as much as a CAD workstation. We'd buy the same kind of color filters used for stage lighting, and cut them down to size. They were a bit delicate, as I recall, so we'd go through them over time. GIMP makes the job a bit easier now than it was with available software of that time. By that I mean it was much more tedious but not a lot more difficult. This is essentially the same way that old 3-strip Technicolor cameras worked, and it's why those old films often look more colorful than today's movies. Three strips of black-and-white film moved through the gargantuan camera at once, behind a beam-splitting prism and color filter, and each negative thus produced was dyed in its complementary color and used to produce a final composite print. It is in fact this last part, the printing with dyes, that gives the rich color that we also see in those old Russian photos. Those Russian photos are notable for being the only truly accurate and saturated full-spectrum photos the world would see until the inventions of Kodachrome and 3-strip Technicolor, both of which came along at about the same time a few decades later.
I did this back in the 80's with my TX1000, a B/W video digitizer card and an old security camera. A programmer friend came up with utility that would take the 3 8bit files and combine them into a 24 bit Targa file. It was fun and color capture was just a little too expensive at that time.

Its not very portable but you can plug a gameboy camera into a Super Nintendo game boy adaptor or gamecube gameboy player and then run the console through a usb capture card to the pc.
Ha! I actually bought a red, green, and blue GB Camera for this exact purpose. :-) I also bought a yellow one because... hey I already had the other three, so why not. But also figured I could use one B&W image as a luminance gain input. Now I just need to find one of those prisms. I'm hoping to work out something where I can initialize the imaging devices and read their output in real time without a host Game Boy, and without modifying the cart. Then I could potentially have a Color GB Video Camera! ;-)
Cctv cameras don't have IR for low light levels directly, they allow the use of IR lighting that humans won't notice but dramatically improves the cctv image.
I was watching again this video after 5 years and since I’m into astrophotography now, I noticed that the color filters are pretty much what we do when taking photo of planets and nebulas nowadays. This enable us to have bigger sensors that get more light since it only have to capture monochrome. 😄
This makes me remember a guy i knew that had a setup just like this for the Amiga. It was in the year of 1990. Just a a couple of days ago i was going thru a buch of old Amiga diskettes and a found a couple of pictures he helped me scan :) This was very expensive hi tech at the time if you did not have an Amiga 500 and a black and white surveillance-camera :)
This method is used in astrophotography along with a luminance channel for brightness and is known as lrgb imaging. Luminance,Red,Green,Blue. Astro filters have uv/ir cut aswell to cut infrared and uv
I remember having a Digi-View set up for the Amiga and I had a B&W camera and the 3 wheel setup and you could get great colour photos. It was an early Digitizer of the day. My camera had a Vidicon tube in it from memory. I still have the old camera somewhere.
James Clerk Maxwell's first attempt at a color photo had messed-up colors for the same reason you had problems. His emulsion was sensitive to invisible wavelengths that his filters were letting through. The Cassini space probe used color filter wheels with a B/W CCD to take color separations. I remember using that GIMP technique to combine them back into color photos after getting them off the Cassini raw-images website. Many of the moons of Saturn don't actually have a lot of color, so the results were sometimes not spectacular--but Titan does.
You could use a spinning wheel with filters mounted in it, and 2 or 3 examples of each color. Driving the wheel with a variable speed motor will allow you to sync the filters speed with the frame rate of the camera. Instead if capturing still images, capture video. Then go and select 3 consecutive frames from the video. The time elapsed between each frame will be miniscule, making movements of human subjects much smaller.
In fact, even "consumer grade" cameras use this technique. There is a filter with a color pattern at the front of the sensor, that assign colors to each pixel separately.
tristan3510 Beam splitting with a dichroic mirror, used in 3CCD cameras, is mentioned in the video. Antoine is talking about the Bayer filter used in most, but not all, single sensor cameras.
I've researched Gorsky's work years ago, pleasantly surprised to find 8-it Guy doing a video mentioning his work. I always loved that bridge shot with the water, looks better than most phone cameras and it was taken over 100 years ago.
So glad to see ma boi Sergi get some love, digitized works are available from the Library of Congress (Amazing story of how they ended up there) though the Russian wiki also has a fantastic portal to his archived work.
Great video! Brings back memories. The DigiView for the Amiga back in the 80's worked in exactly the same way, it came with a perspex colour wheel that attached to the front of the camera. You could get an optional motor that automatically turned the wheel to the next colour. (High Tech!!) I worked for an Amiga dealer here in the UK at the time and had to set one up for a wealthy customer. He tipped me £20, I was 17 and earning £40 a week back then!!
I worked in a photo studio for a drugstore chain in the late 90s. They primarily photographed products for advertising. They mostly used a very high resolution (for the time) digital B/W camera with an automated color wheel that took three shots that were combined in the computer.
not really. blow the transistors and other components of the phone to the proportion of those older cameras and you've got hardware that's a million times bigger than the former
The Stickman Gaming But why blow them up to proportions? They’re not that big, so it doesn’t make sense why they would be bigger than these old cameras.
This brought back memories of my days back around 1989 when we used an Amiga 2000 desktop and a B/W camera mounted on a vertical stand to digitise artwork from printed material/photos etc (using RGB filters) ---this method--- to create animation and/or Transparencies to overlay on analogue video for advertising . This is very easy and common thing now you see on News channels ....where the Headlines are super-imposed on the video of News reader........sorry ...for lengthy disc....Memories of my Video Studio.
Same here. I used DigiView and DigiPaint on my A1000 for lots of artwork and it involved a 4-segment plexiglass filter (clear, red green and blue). And the results were amazing! I could also take my camcorder out at the fields and record still shots with the filter attached to the lens, and digitize them at home afterwards. Time-consuming, but rewarding.
That’s how we digitized pictures in the 80s. On the amiga, you could get a digiview that had those same 3 color “wheels”. Great for digitizing static pictures, but nothing else
I remember using this technique to get photos into my Amiga 1000 before scanners were available. I also had a flat bed scanner back in the 1990's that took three passes using RGB filters between each pass to compose the resulting color image.
I used the ECS (Electronic Color Splitter) with my Digiview Gold to do the same thing to grab color frames from my VCR. Not as sharp an image as you could get with the monochrome camera and the included color wheels, but I was mostly after video snapshots.
If you wanted to see what it would look like, you could take your 3 black and white images taken with a camera and reduce it to 2bits per pixel, then apply the compose. Here is an article I found of someone using the GB camera to do the techniques in the video though: www.wired.com/2014/06/game-boy-camera-color/
The effect of the different colours being a bit out of line with each other is actually pretty cool and trippy! I wonder what it would look like if you took a photo of three different people in the same position with one filter each.
Interestingly this method of colour photography is still more or less the de-facto standard in astronomy, both Earth-based as well as space telescopes like Hubble, and also for an overwhelming amount of scientific and medical imaging, this is still the way it's done. Technically *all* digital image sensors are monochrome, there's no such thing as a digital colour sensor. "Colour" sensors are really just monochrome sensors with a checkerboard of RGB filters literally glued onto the sensor pixel wells, it's called a Bayer array, which is then processed by the camera processor to do what you did in this video basically. And yes, that means the pixel resolution of a colour image sensor is divided into at least 3 different colours, but thanks to math and algorithm magic, you still get a useable resolution that is very close to the "spec sheet" resolution. Anyhow, the preference for monochrome sensors is due to them usually being a lot more sensitive to light, and depending on various other factors and requirements, there are many other benefits to monochrome sensors as well. Furthermore, since a "naked" sensor will just capture ALL the light it sees, it means you are not only limited to Red, Green and Blue, but also UV, IR, and even specific single wavelengths of light of interest (H-α spectral lines are a favourite in astronomy for example). Most telescopes, both amateur and big huge scientific telescopes, as well as space telescopes, have filter wheels. These filter wheels can accept basically any combination of filters that you desire, and, as the name suggests, it's a wheel that can just rotate the filter you want into place, and off you go. You can then combine all this raw data in any way you want, including creating natural colour photographs of things. Or, composing photographs that are based on non-human-visible colours such as UV and far-Infrared, or whatever absorption/emission spectral lines you want really, into something that we can view and comprehend. Sadly the latter usually gets misunderstood by the general public, and you end up with misinformation along the lines of "those beautiful Hubble pictures of galaxies and nebulas are fake colours" ... Well, not true, it's just not literally RGB filters, it's a combination of dozens of spectra, mapped onto a human-visible spectrum. Just because our crappy human eyes can't see those wavelengths of light doesn't mean they are not there. Anyway, just thought that might be an interesting extra bit on top of what you showed in this video. It's a straightforward and neat technique, and it's fascinating that it is just as useful today as it was over 100 years ago, and likely it will be just as relevant 100 years from now.
Thanks for the excellent explanation. I too dislike all the "fakery" shouts when Hubble pics are displayed. Yes indeed, those nebulae and galaxies look like that... if our eyes could deal with IR and UV. Even X and u-waves.
I rather like how the camera gives the color images a very natural grainy look. combined with the nature of the filter method being used it makes for some very interesting images. Gotta love using old, leftover equipment for crazy stuff like this.
Those 110 year old photos look better than photos from some cameras today.
When light projects onto film there is infinite resolution as it takes in all light while digital is due limits on pixels
dan i know right

Hence the need to add filters (including bayer) to reproduce colour. Normally there is also an IR filter (astro photography excepted) added as well, to keep colour reproduction more accurate.
I thought so. The look totally reminds me of Voyager and Mars Rover photos.

They also converted it to broadcast color with a camera aimed at a screen at Mission Control. Occasionally some white space debris would fly through the view and appear as sequential red, green, and blue dots.
Monochrome cameras are also used in astronomy due to the higher resolution given. All pixels are one colour over 2* or more images, rather than a mix of red/green/blue in the one image. Essentially, a Bayer filter divides a sensor into 3, so an 18 megapixel sensor is really only capturing 6 megapixels per colour. A monochrome sensor using individual filters, 18 megapixels are captured per colour.
*Sometimes, only 2 colours are used for astronomical images. Consisting of one red exposure and one blue exposure. The red and blue can then be combined to create or extrapolate the green image..
This is the principle as when taking astrophotos with non-RGB sensors.
Just to make it a bit harder for you, Red, Green and Blue don't have the same focal point due to its wavelength.
I'm reminded of a very early attempt at color TV by using a color wheel in front of a B/W TV, and an identical wheel in front of the B/W camera. As it spun, the TV would display the red, green and blue images alternately and the color wheel would show them in the correct color. Due to persistence of vision, you'd see a full color image. It was a good idea in theory, but in practice keeping the wheels in sync between the camera and the TV screen proved next to impossible; not to mention the horrible flickering effect!
Tomsonic41 It wasn’t just an attempt. CBS made history’s first color broadcast using this format. That was 1950, nine years after system ‘M’ was adopted. The market chose to abandon the color wheel system for its lack of backwards compatibility, not its flickering. I’ve seen one demonstrated though, and the color artifacts are not distracting. It’s actually quite crisp.
Even the newest generation of laser projectors still have wheels.
The Apollo Moon missions sent color video back from the Moon using a version of this method. The color video cameras of the time were far too massive and bulky to take on a spacecraft, but there were B/W video cameras that were relatively compact, and they used the color-wheel method to get video separations and combined them using a lot of analog video wizardry Earthside. (If I recall correctly, part of the process literally involved correcting for Doppler shift by adjusting the slack in a strip of videotape.)
DLP projectors work pretty much the same
yes a lot of DLP projectors used color wheels, I can't stand them because I can actually see the color tearing sometimes... this isn't a problem with 3DLP projectors since they use a trichro like the 3CCD cameras referred to in the video
I just knew this would showcase Prokudin-Gorsky's work. The people photos he took are impressive when you think about taking 3 exposures in a row with really slow chemistry. The filters slowed his exposure even more.
It’s true, but Prokudin-Gorsky took advantage of using silver bromide based negatives, they were more sensitive to light, which helped to decrease exposure time a bit. It definitely wasn’t fast, but considering that he needed to take 3 shots each time, it helped quite a lot.
probably thats the reason why most of his images are in bright sunlight.
Very satisfying... even with colorblindness 🤦♂️😉 The lens flare shot is actually very cool!
So your color blind, did not know that, and i have seen more then a few video's of you, and which colors do you not see?
Is there something in retro computers that give color blindness?
The term colourblind is a misnomer, as it doesn't mean we can't see those colours, it just means certain colours are confusing, and we can't always see the differences.
Aha ok, but you say you can't see the difference between some colors, that means you do not see the right color, so then the word colorblind is the right work no?
I wouldn't say it's a misnomer. Monochromacy (only seeing greys) exists, it's just very rare. Most people who are color blind can still see color, but the colors they can see are limited, so they are blind to those colors, at least.
You can also make red-blue 3-D pictures, just move camera few centimetres between pics.
B&W shot through color filters is how the color vector graphics you see in TRON were created (when Flynn has been digitized and is flying down to the Game Grid). Robert Abel & Associates created those images on the Evans & Sutherland Picture System, which was a 3D workstation built for tasks like CAD and flight simulation. It uses a B&W vectorscope display. RAA photographed these images directly off the monitor with the use of RGB filtration, shooting a pass, rolling the film back and shooting the next color record. It was time consuming but it worked and created a very specific aesthetic that's difficult to reproduce with modern motion graphics.
In 1950 CBS labs invented a color television system that used the same "sequential color" system, with a color wheel spinning in front of the image sensor on the camera, as well as a larger filter spinning in front of the display CRT. The system failed because it was not compatible with existing B&W TV's.
The system was modified and updated by Westinghouse and used during the Apollo program to allow live color pictures from the Moon, as well as live color close up pictures of the launch from a camera mounted on the launch tower.
To make standard broadcast NTSC color first an arrangement like the CBS system was used with a color wheel on the converter camera and on the display tube, then by Apollo 14 RCA had developed a digital system that used (non imaging) CCD's and RAM to store the frames of video then combine them digitally.
Color fringing will always be a problem with sequential color systems since each frame is taken at a different time and the subject may be in a different position.
mspysu79 [Automatic answer to a comment mentionning Apollo 11 and the Moon]
No you sheepie wake up we never went to the Moon fake Nasa liars lol
[insert a bunch of "proofs"]
Here are the first Color TV pictures from space using the Westinghouse camera with the sequential color wheel. You can see it at 10:00. czcams.com/video/KbGHIQvObN0/video.html
These old photographs fascinate me. Then I called my brother to look at them and guess the age of the photo, and he was totally wrong, and wide-opened his eyes in surprise when I told him these are over 100 years old.
Cool seeing my town of Ft Worth thru the lense of my favorite CZcamsr
These photos look like they have been taken in the 80's! That is totally amazing!!! Honestly, you did an excellent work, sir!
I went to a museum which was showing photos by Sergey Produkin-Gorsky, they were otherworldly, color photos from a totally different world!
The color fringing actually looks super cool though. I'm gonna remember that technique for later.
Carpoolparty Old TV shows shot on analog color cameras had this look. Lots of ‘70s sitcoms and dramas, especially. The fringing wasn’t this bad, though.
its also really easy to replicate the effect in post with photoshop or some other photo editing software, always good to give an image that extra retro flair haha.
Carpoolparty its called chromatic abberation :)
That could be used in a music video
If you want to, you can easily replicate the effect with a regular colour camera. The red, blue and green channels of a colour image can easily be separated by Gimp and then you can combine the channels from different pictures just like in this video.
6:15 is such an interesting picture. The subject came out great, it's got that grainy 70's home video look (the shorts help even more!), and the filter flares occur in a way that really adds to the picture. Very nice.
Thank you for mentioning Sergey Prokudin-Gorsky-although you pronounced his name not quite correctly ;)
I admire this guy and his work ever since I’ve seen his photographs the first time many years ago.
Btw: Most of his work you can find online today was digitally composed from the original black-and-white parts. Back in the days, such a perfect and flawless composition of all three components was not possible.
Amiga, Newtek, DigiDroid....1988. I still have it, the Amiga 1000, and the Panasonic staticon tube B&W security camera we used it with.
Color images from satellites like Himawari are composed exactly this way. The multi spectral cameras use multiple filters for red, green, blue and many near and far infrared wavelengths. If they combine the 3 color channels were get a color image from the earth.
iirc somewhere on the net is a satellite photo that shows a jet with color fringing due to the multiple exposures required.
Almost all telescopes, both Earth-based and the ones in space, use monochrome sensors + filter wheels. It's the way it has always been done, and probably the way it will always be done. Monochrome image sensors are just superior in many ways. It's also easier to create very high-quality filters that are external, and you can put them in a filter wheel to have dozens of filters available, that can automatically be rotated around as required by the telescope.
This is how we used to get color scans from a black-and-white flatbed scanner back in the day. Nobody had a color scanner in the eighties, when they probably cost almost as much as a CAD workstation. We'd buy the same kind of color filters used for stage lighting, and cut them down to size. They were a bit delicate, as I recall, so we'd go through them over time. GIMP makes the job a bit easier now than it was with available software of that time. By that I mean it was much more tedious but not a lot more difficult.
This is essentially the same way that old 3-strip Technicolor cameras worked, and it's why those old films often look more colorful than today's movies. Three strips of black-and-white film moved through the gargantuan camera at once, behind a beam-splitting prism and color filter, and each negative thus produced was dyed in its complementary color and used to produce a final composite print. It is in fact this last part, the printing with dyes, that gives the rich color that we also see in those old Russian photos. Those Russian photos are notable for being the only truly accurate and saturated full-spectrum photos the world would see until the inventions of Kodachrome and 3-strip Technicolor, both of which came along at about the same time a few decades later.
1. Those indoor pics of Jordan would make cool album art.
2. You should take pics using just IR/UV and blocking out the regular spectrum
I did this back in the 80's with my TX1000, a B/W video digitizer card and an old security camera. A programmer friend came up with utility that would take the 3 8bit files and combine them into a 24 bit Targa file. It was fun and color capture was just a little too expensive at that time.
These old photos were amazing. Hard to believe, that they are that old. Very good video, thanks!
This video blew my mind absolutely amazing this is the kind of content I look for on CZcams I’m at a loss for words this was a good watch thank you so much and please keep making interesting videos like this you inspire me to get out there and restore and fall in love with these old but beautiful machines thank you again The 8-Bit Guy
This was a wonderful, and well put together video. It really helped me understand this concept! Thank You, The 8-Bit Guy!
Trying to get a teenager to stand still... That could be an entire video... Great job, I love the video!
The Heck is wrong with you? Get your shit together and get lost. At least before you get banned.
Fucking Hell man, God I hope you're just trolling. Not everyone can stand perfectly still, Autism has nothing to do with it
Doot the dooter I'm sure he was flailing wildly as he typed that out lol
Requim Dream 6:22 LOL WTF does clouds have autism in my day cloud stood still at all times now they move because wind?? lol something wrong with cloud clock tower can stand still just fine
Dude I did not know about those old colour pictures. Those look awesome.
This has to be one of the coolest videos you've done. Thank you. 😊
Wow, this photos literally there made before USSR existed
I've seen this done with the GameBoy Camera before, always wanted to try it.
Was about to say the same thing I remember the site that has a tutorial on the process and have always been tempted to try the process
Trekeyus Yeah, sadly I have no way to get the GB Camera photos onto my PC.
mystman12 look into the ASM retro altane or that thingy that emulates the gb printer and prints to imagine files on an SD card
Its not very portable but you can plug a gameboy camera into a Super Nintendo game boy adaptor or gamecube gameboy player and then run the console through a usb capture card to the pc.
Ha! I actually bought a red, green, and blue GB Camera for this exact purpose. :-) I also bought a yellow one because... hey I already had the other three, so why not. But also figured I could use one B&W image as a luminance gain input.
Now I just need to find one of those prisms.
I'm hoping to work out something where I can initialize the imaging devices and read their output in real time without a host Game Boy, and without modifying the cart. Then I could potentially have a Color GB Video Camera! ;-)
Cctv cameras don't have IR for low light levels directly, they allow the use of IR lighting that humans won't notice but dramatically improves the cctv image.
one of your most amazing videos!
I was watching again this video after 5 years and since I’m into astrophotography now, I noticed that the color filters are pretty much what we do when taking photo of planets and nebulas nowadays. This enable us to have bigger sensors that get more light since it only have to capture monochrome. 😄
I really don't know why I watch your videos... but I'm never disappointed.
Color from B&W?
"Ooooooh, CAN DO! I'm Mr. Meeseeks . Look at me!!!"
Cool, I love the look it gives that camera. Could totally create some retro-style videos this way.
I seriously love your videos!!
I get excited everytime I see the 8-bit Guy in my notifications!
Same
This makes me remember a guy i knew that had a setup just like this for the Amiga. It was in the year of 1990. Just a a couple of days ago i was going thru a buch of old Amiga diskettes and a found a couple of pictures he helped me scan :) This was very expensive hi tech at the time if you did not have an Amiga 500 and a black and white surveillance-camera :)
You know what man. You bring back a lot of good memories. Thank you
This method is used in astrophotography along with a luminance channel for brightness and is known as lrgb imaging. Luminance,Red,Green,Blue. Astro filters have uv/ir cut aswell to cut infrared and uv
The most like minded CZcams channel I have ever found.
5:12 okay, this is the method I need to use for the cover of my synthwave record.
Wow! What a beautiful photographing technique! 😮 Amazing to see such beautiful results with it! 🙂
I remember having a Digi-View set up for the Amiga and I had a B&W camera and the 3 wheel setup and you could get great colour photos. It was an early Digitizer of the day. My camera had a Vidicon tube in it from memory. I still have the old camera somewhere.
Nice, mentioning Prokudin-Gorskij! The quality of his photos is really amazing.
James Clerk Maxwell's first attempt at a color photo had messed-up colors for the same reason you had problems. His emulsion was sensitive to invisible wavelengths that his filters were letting through.
The Cassini space probe used color filter wheels with a B/W CCD to take color separations. I remember using that GIMP technique to combine them back into color photos after getting them off the Cassini raw-images website. Many of the moons of Saturn don't actually have a lot of color, so the results were sometimes not spectacular--but Titan does.
Found your channel by occasion. I'm glad I did, what a good content! I feel like I'm watching my favorite arts professor from High School!!!
Glad you are back David.
Lies. Everybody knows that the world was black and white before 1950. :D
Yes. Totally fake. In real life Rubik's Snake contains only two colors en.wikipedia.org/wiki/Rubik%27s_Snake.
Except color movies were popular since the 30s.
@@MarkBaldridge r/woooosh
And everybody was an expert dancer, doing back flips and tumbles in a fully choreographed routine at a typical high school dance.
Wizard of Oz?
Fascinating!
Very fascinating. It really is impressive how good those old color photos look.
You could use a spinning wheel with filters mounted in it, and 2 or 3 examples of each color.
Driving the wheel with a variable speed motor will allow you to sync the filters speed with the frame rate of the camera.
Instead if capturing still images, capture video.
Then go and select 3 consecutive frames from the video.
The time elapsed between each frame will be miniscule, making movements of human subjects much smaller.
a mexican did this in 1938 and created the very first color tv system
+0X29Adecay Trichromatic Color System, designed and patented by Gullermo Gonzalez Camarena
Or blend the frames in Gimp for 10fps color video!
In fact, even "consumer grade" cameras use this technique. There is a filter with a color pattern at the front of the sensor, that assign colors to each pixel separately.
tristan3510 yes but he explained that professional cameras had 3 sensors, one for each color, so it is a different system
tristan3510 Beam splitting with a dichroic mirror, used in 3CCD cameras, is mentioned in the video. Antoine is talking about the Bayer filter used in most, but not all, single sensor cameras.
I am a photographer and loved this video ... Great Work. Will love to work on your challenge.
Absolutely amazing, probably one of the most interesting video I've ever saw.
I've researched Gorsky's work years ago, pleasantly surprised to find 8-it Guy doing a video mentioning his work. I always loved that bridge shot with the water, looks better than most phone cameras and it was taken over 100 years ago.
So glad to see ma boi Sergi get some love, digitized works are available from the Library of Congress (Amazing story of how they ended up there) though the Russian wiki also has a fantastic portal to his archived work.
This is exactly how the old NewTek DigiView scanner/digitizer for the Amiga worked.
I was also left scratching my head by the previous video. Thanks for this follow up
Great video! Brings back memories. The DigiView for the Amiga back in the 80's worked in exactly the same way, it came with a perspex colour wheel that attached to the front of the camera. You could get an optional motor that automatically turned the wheel to the next colour. (High Tech!!) I worked for an Amiga dealer here in the UK at the time and had to set one up for a wealthy customer. He tipped me £20, I was 17 and earning £40 a week back then!!
Yeah, I think that's awesome.
I'm no photographer, but I know a few people that would love this sort of challenge.
Just fyi, at least in the UK, 'glamour model' means someone who appears in photos you find in playboy.
Skellious oof
It's the same here - though plenty of people are not familiar with the term
I'm a glamour model for a Japanese magazine that specialises in long men hair, it's gross what some people will get into but money is money
Not even remotely the definition in North America.
Glamour implies the photography is erotic xD
I worked in a photo studio for a drugstore chain in the late 90s. They primarily photographed products for advertising. They mostly used a very high resolution (for the time) digital B/W camera with an automated color wheel that took three shots that were combined in the computer.
This is an amazing experiment! I finally understand how a color photos works with only black and white camera
Damn... these 110 y/o photos still look better than what my phone captures
but the hardware used for those photos take up 10000x more space than a phone
not really. blow the transistors and other components of the phone to the proportion of those older cameras and you've got hardware that's a million times bigger than the former
The Stickman Gaming You know phone cameras don’t take up much space, right?
you know what blowing to proportions means right?
The Stickman Gaming But why blow them up to proportions? They’re not that big, so it doesn’t make sense why they would be bigger than these old cameras.
This brought back memories of my days back around 1989 when we used an Amiga 2000 desktop and a B/W camera mounted on a vertical stand to digitise artwork from printed material/photos etc (using RGB filters) ---this method--- to create animation and/or Transparencies to overlay on analogue video for advertising . This is very easy and common thing now you see on News channels ....where the Headlines are super-imposed on the video of News reader........sorry ...for lengthy disc....Memories of my Video Studio.
Same here. I used DigiView and DigiPaint on my A1000 for lots of artwork and it involved a 4-segment plexiglass filter (clear, red green and blue). And the results were amazing! I could also take my camcorder out at the fields and record still shots with the filter attached to the lens, and digitize them at home afterwards. Time-consuming, but rewarding.
Love this channel.
Super informational.
That’s how we digitized pictures in the 80s. On the amiga, you could get a digiview that had those same 3 color “wheels”. Great for digitizing static pictures, but nothing else
I remember using this technique to get photos into my Amiga 1000 before scanners were available. I also had a flat bed scanner back in the 1990's that took three passes using RGB filters between each pass to compose the resulting color image.
Same here. I still have my Digi-View in my basement along with the camera. Threw the stand out for some reason. Not sure about the color wheel.
NewTek even had a motorized option for the color wheel. I was too cheap, but had the rest of the gear on my 1000.
I used the ECS (Electronic Color Splitter) with my Digiview Gold to do the same thing to grab color frames from my VCR. Not as sharp an image as you could get with the monochrome camera and the included color wheels, but I was mostly after video snapshots.
Wouldn't the real challenge be taking good color photos with the gameboy camera? ;)
Would not have a high amount of colours or resolution.
If you wanted to see what it would look like, you could take your 3 black and white images taken with a camera and reduce it to 2bits per pixel, then apply the compose. Here is an article I found of someone using the GB camera to do the techniques in the video though: www.wired.com/2014/06/game-boy-camera-color/
People have actually tried that
The effect of the different colours being a bit out of line with each other is actually pretty cool and trippy! I wonder what it would look like if you took a photo of three different people in the same position with one filter each.
What an amazing episode!!! Greetings from Bogotá, Colombia
Using a hires B/W camera is done in Astronomy with filters.
"Hires" as in _high-resolution_ not "hires" as in _employs_ .
I'm old 'n slow. Took me a second to figure out what you meant. Maybe "hi-res"?
Interestingly this method of colour photography is still more or less the de-facto standard in astronomy, both Earth-based as well as space telescopes like Hubble, and also for an overwhelming amount of scientific and medical imaging, this is still the way it's done.
Technically *all* digital image sensors are monochrome, there's no such thing as a digital colour sensor. "Colour" sensors are really just monochrome sensors with a checkerboard of RGB filters literally glued onto the sensor pixel wells, it's called a Bayer array, which is then processed by the camera processor to do what you did in this video basically. And yes, that means the pixel resolution of a colour image sensor is divided into at least 3 different colours, but thanks to math and algorithm magic, you still get a useable resolution that is very close to the "spec sheet" resolution.
Anyhow, the preference for monochrome sensors is due to them usually being a lot more sensitive to light, and depending on various other factors and requirements, there are many other benefits to monochrome sensors as well. Furthermore, since a "naked" sensor will just capture ALL the light it sees, it means you are not only limited to Red, Green and Blue, but also UV, IR, and even specific single wavelengths of light of interest (H-α spectral lines are a favourite in astronomy for example). Most telescopes, both amateur and big huge scientific telescopes, as well as space telescopes, have filter wheels. These filter wheels can accept basically any combination of filters that you desire, and, as the name suggests, it's a wheel that can just rotate the filter you want into place, and off you go. You can then combine all this raw data in any way you want, including creating natural colour photographs of things. Or, composing photographs that are based on non-human-visible colours such as UV and far-Infrared, or whatever absorption/emission spectral lines you want really, into something that we can view and comprehend. Sadly the latter usually gets misunderstood by the general public, and you end up with misinformation along the lines of "those beautiful Hubble pictures of galaxies and nebulas are fake colours" ... Well, not true, it's just not literally RGB filters, it's a combination of dozens of spectra, mapped onto a human-visible spectrum. Just because our crappy human eyes can't see those wavelengths of light doesn't mean they are not there.
Anyway, just thought that might be an interesting extra bit on top of what you showed in this video. It's a straightforward and neat technique, and it's fascinating that it is just as useful today as it was over 100 years ago, and likely it will be just as relevant 100 years from now.
Thanks for the excellent explanation. I too dislike all the "fakery" shouts when Hubble pics are displayed. Yes indeed, those nebulae and galaxies look like that... if our eyes could deal with IR and UV. Even X and u-waves.
I rather like how the camera gives the color images a very natural grainy look. combined with the nature of the filter method being used it makes for some very interesting images. Gotta love using old, leftover equipment for crazy stuff like this.
That would be cool to see color with a gameboy camera.
