cazillo.com/art... Histograms are the only way when shooting to get an accurate representation of your exposure. Without it, you could look at your screen and think your photo is exposed properly but then look at them on your computer later and realize everything was underexposed or overexposed.
In my business, I've heard from a hundred teachers, instructor, professors, trainers and self-proclaimed experts, and not all of them were able to get the lesson across.....No matter what profession YOU may have chosen, I believe you would be able to share your knowledge.....You seem to have that "gift" of being able to teach. And I think that gift truly is a gift, it can't be learned. I look forward to some more free time to watch your videos...
i like how you were not reading this information from anywhere, which shows that you actually know and understand what you are talking about. good job greg keep it up learning lots from you!
I have never seen anyone else describing how this works and I'm very grateful for the help. Thanks.
Thanks Greg I've been shooting for almost 3 years now and I've only learned to start using my camera's histogram about a month ago. This was immensely useful.
that is a good theoretical explanation.what i recommend is getting a gray card and meter with its help and learn by looking and understanding the results with it. i am not a big fan of 'oh my histogram has a flat spot on the right, that means i have to exposure the same image again but a stop longer and later in photoshop i just shift my histogram some way'.
i think most people dont know that you meter for the amount of light you got and not for the light reflected by the shooting subjects.
Excellent - I had problems understanding histograms with the other tutorials, but now I'm understanding it properly after watching your video.
Many thanks and well done.
I forgot to come back and say thank you for helping me understand Histogram, you made it so easy to understand what it is and I always recall this video in my memory when reviewing it on my cameras LCD screen.
+oitsonlikedonkeykong Glad I could help, did you see the new version of this video? It kicked off a whole new series of videos! czcams.com/video/QIS6N_-75Ew/video.html
I was trying to shoot toward the center of the histogram, but now that you've explained that the majority oft the info is to the right, and you can tailor it down in Lightroom or Photoshop to what you like using the 55 gal drum analogy, it makes sense to me now. Thanks again.
Thank you very much! The whole "half the data is on the first stop in the file" is such a revelation to me, no one else talks about this (except for maybe real photography classes [which is pretty much what this is]); I am very grateful for this video. Only I wish I had seen it before going out to shoot this morning.
this video makes me feel better about histograms, becoz before this video i never cared of my histograms while shooting..thnks u greg
Just watched this again, I thought he first time I watched it I understood it pretty well. But after shooting and using my histogram I realized that I needed a bit more info. Your series on exposure is bang on. There are those putting up videos on exposure lately that say don't use your histogram and recently one said don't use your light,eter?? You should be able to get the right exposure by taking three shots and chiming each one till you get it right..... I am great full for your knowledge a
Wow, I didn't know half of the data was in the far right section of the histogram. I am thinking back and realizing I have left out half the data on a lot of my shots! This video will greatly improve my photography!
Great job. I always shoot with my histogram displaying on the camera so I can see where I'm at. Your comments on shooting for the high end of exposure and making adjustments to the image in Lightroom are very helpful. I shoot with a Cannon 7D
I may have not agreed with a few things you have said in other videos, but I must say, this is the best video on photography online. This is about my 4th time watching it....If I could recommend one video to a new photographer this would be it. Good Job...
Hi there Greg, this is the best histogram explanation I've seen yet. I'm a lot wiser now. I'm just learning how to use my Canon SX 40.
After seeing the simplicity of they way you presented this topic - automatically subscribed. Good job
I only knew the basics of what a histogram is so this was great. Keep up the good work Greg!
Wicked tutorial. Up to now I have been shooting everything 2/3 of a stop underexposed; purposely. I got that technique from watching Bryan Peterson. Little did I know that should only be used for my sunsets and sunrises. Thanks for the vid
I am from colombia and i wanna thank you for sharing your knowledge, this vídeo is so useful
you might be my new favorite person...watched 2 videos so far...gonna watch all of them and then i'm sure i'll be asking questions....thanks so much!!!
Shooting to right of histogram needs practice. It's easy to be very right. Overexposed images can't be recovered like underexposed. I like that you mentioned that image processing destroys the quality. Except some basic corrections of the raw file.
Very helpful video 👏.
+Dimos Labrou Thanks for watching!
I may be wrong but it's underexposed can't be recovered like overexposed, right? And yes, the video was very helpful. Thank you, Gregory. +Dimos Labrou +Gregory Cazillo
I watched this video while listening to Katy Perry - Firework in the background. Definitely made the video more of an enjoying watch. Greg, you're a firework!
Finally someone explained me how this histogram stuff works! Great video!
This video was very good, im in the process of learning how to become a better photographer, even with practice I never understood histograms. This explained it perfectly, you sir have earned a sub.
Very informative explanation. I felt like I was sitting in a class some where. I stumbled on to your video, now a subscriber!
Excellent presentation. I am new to digital photography and this is the first video I've watched regarding histograms. You explained things very clearly. I loved your visual examples. Gonna check out some of your other tutorials. Thanks a lot.
@WarrenAckary180 it means moving the data to the right of the histogram, not underexposing which would leave a flat spot on the right side. Rewatch the last segment which shows a few photos underexposed through edited.
man i am glad that people like u are giving honest lessons. great info thanks alot n blesw u
@WATSABI0 You should be using the in camera meter BEFORE taking the photograph, then if you need to evaluate that exposure with the histogram AFTER the image has been taken. I use the histogram to evaluate a scene to check my exposure, then finish shooting in that particular scene without rechecking as long as the light or other factors haven't changed.
Great explanation and examples. I didn't know about the high range half data thing but I can understand why. Thanks Greg!
Ok Greg, that makes sense, yeah can be a little bit confusing for beginners also subtle. When I was saying I am always using it, I meant outside for landscape photography (example with fushia flowers). Like you I don´t use it for my studio work where everything can be controled ( light, color chart, etc ... )
Keep up the good work !
WOW!!! that brought a tear to my eye, my problems CAN be found now, THANK YOU!!
really nice explanation, just need more examples of pictures under and overexposed. Now i understand the flat spots of under exposure. Nice work!
@Pur3Kiwi shooting to the right means adjusting exposure so you don't have flat spots on the right side of the histogram. It is image dependent meaning the way you want to create the image takes precedence over how the histogram looks.
Gday from Australia. Was searching info on evaluative and spot metering and found your channel. Watched that one and then watched this one. After viewing these 2, I've hit the subscribe button. Mate you put it in such easy to understand terms. I'm off now to play with my 550D and see if I can remember what I've just learnt!
great, well articulated lesson. You are a great teacher and do an amazing job conveying this info. Thanks for your help.
The height of the lines depend on luminance and saturation of the colors in that part of the image. They can't always be controlled nor would you want to artificially increase them unless you want increased saturation or color in that area of the photo.
@opulido104 As I replied to someone else...its all about how you like your images. Just don't rely on your screen, thats what the histo is for.
"Everything is relative and you need to figure out how you like your images. You should use the lcd and the histogram to judge exposure, there is no right answer for every image you just need to get more experience setting your camera to what you like."
I had played with UniWB in the past but didn't see a difference in my images. It might help others who shoot more landscape or product, but I am happy with my single (not RGB) histogram. It is very rare that it is that far off to potentially ruine an image.
going to add your question to my list for an upcoming keep shooting monday video. You need to use a few things to get good exposures.
1. experience
2. meter
3. histogram
4. creativity
Thanks, Greg, you've shared very valuable information here in a very well explained manner. Good job, keep up the good work.
No it means checking your histogram to make sure it is to the right. If its not you will have to adjust your exposure which might require you to use exposure compensation. Hopefully you can understand the difference between the two even know they are linked.
@JanErikEdvartsen It depends on the image. If the clipping is because of some lights in the ceiling then don't worry about it. If its because of someone's white shirt or a bride's dress then you need to be careful and keep the detail. Some detail can be brought back but it depends on how overexposed it is. If the spike is 3/4 of the height of the histo then not all of it is coming back.
Did I answer your question?
ur a far better teacher than the fro.... keep up d good work...
I'm just now realizing that I've been underexposing for way too long. I just read Michael Reichmann's essay called "Optimizing Exposure" (www.luminous-landscape.com/tutorials/optimizing_exposure.shtml) and I then poked around here to see if I could find anything to drive his point home. This video does just that. Greg, this was really really helpful. Strong, clear and to the point - without too much technical information. I just subscribed, too. THANKS!!!
Thanks for the video! I'm not rich but I would pay to subscribe to your channel. I appreciate the time and effort you take to make these videos to help the rest of us to be better photographers. Keep up the outstanding work Greg!
'There is no absolute in photography and anyone who tells you that is full of crap' ....LOL love it. Great tutorial!
Thanks Greg. Very informative video. This will most definitely help me when I shoot from now on.
Greg, I find your presentation refreshing and will look further ........
Very nice explanation. Congratulations !!!
I always want to understand the histograms of my photos and now you help me a lot. Thx !
Hey Greg, just discovered your tutorial series. I am excited to see the rest of your videos, but I really enjoyed this one. I'll definitely have to look into "shooting right" a bit more to understand it completely. Anyways, thanks for sharing with us!
Greg: Great video. "Shoot to the right." I had never heard it explained that way before. I enjoy all your videos. Keep it up, and have a great Memorial Day weekend.
awesome video, have to watch it again to fully understand it, but now i have a little bit of an idea what that histogram means!
thanks very much!!!!!
@ErnieCosmo In my example I adjusted the black levels, but any of the image adjustments will affect how the histogram looks.
@heycharityo Using different metering modes may or may not give you a better result. For example if using spot metering on a white shirt vs black shirt it would be different exposures. Most of my photos I shoot matrix metering (whole scene) and then compensate from there. Best case is to shoot your photo, check the histogram, then adjust exposure accordingly for the rest of the images in that scene.
Glad you don't have Jared to block your great knowledge anymore...quite frankly the Fro Knows Photo show has become boring...this is real stuff a photographer must know
you are an amazing teacher Greg
@valdezapg Everything is relative and you need to figure out how you like your images. You should use the lcd and the histogram to judge exposure, there is no right answer for every image you just need to get more experience setting your camera to what you like.
I really like this video. I like your presentation skills. And I respect the fact that you took the time and effort to break it down for us noobs. I'm a beginning / aspiring photographer. Thank you again. I hope you are still active, as I see this is from 2011. But after this one and a few other, I'm subbing.
What a great story. I have visited John Muirs beautiful home, I too love the nature.
Awesome videos Greg, please keep them coming, learning so much from you!!!
Very good video. I am just learning this stuff, and being a newbie and not having the "eye" for under over exposed this is pretty good information. So many variables that affect the exposure, that seems where it gets tricky which one do we adjust. I know no right or wrong answer.
thank you very much greg
ive been waiting for this explanation for ages
@earliozz Thats the goal, for everyone to learn something from each video.
great job Greg, love your videos they have helped me a lot, thank you.
I feel like I should be paying for these lessons. Thanks greg!!
Fantastic video Greg! Examples help a million. Keep up the good work man
@Wuzzysbrand06 ideally you don't want to do either, but get a perfect exposure. You lose data with over or underexposure which is why I talked about clipping.
I am hooked...learning a lot from your videos...Thanks
Greg,
Great video, alot of thing about my images are making so much sense now.
Thank and keep the videos coming
Great explanations... Thank you so much, Greg.
Thanks for the nice walk-through, Greg!
@plawkzer Higher lines or areas mean more saturation/luminance in that color range.
Greg, your video/tutorials are great!
Congrats!
Just Subscribed Greg, Thank you for taking the time to teach photography, I really learn alot from these vids.. Please keep it up
great job Greg! definitely learned ALOT right now.
I love my histogram! I gack when I see people shooting video without it. I got some footage from a camera dude to color once, and it was so underexposed that not only was noise an issue but after increasing the exposure in post you could see the tonal steps (much like what you see when running a monitor in 256 colour mode).
Subscribed!!! Man, you are an awesome teacher. Keep relating the photographic-expressions to real stuff everybody can relate to. Like 11:46 !
I don't use the RGB histogram, only the single color one. Middle doesn't matter as much as pushing data to the right without overexposing and clipping highlights or important data.
Using the histogram isn't about 'shooting a stop to the right' its about making sure you have the proper exposure for the photograph you want to create. Yes it can apply to video. Basically if you underexpose video or stills you will have more noise and less color.
@optix1973 I don't see how you can use the histogram on the camera to match a color. That should be a post processing task, not in camera. To match colors you would use a gray card or color checker chart to make sure your white balance is accurate.
Some people do prefer the RGB histogram because it allows you to see where each color is at, especially if its spiking. Just not my preference...
Thank you! That was very useful & easy to understand.
Great Job Greg! I learned alot from this vid!! I will now look @ that now that I know what it means..
You are the man! This was a well lesson learned. Thanks Greg!
@WATSABI0 Nope, histograms are for evaluating images after exposure. Not sure what to tell you about the shoot, hopefully there is plenty of light if not make sure you keep your shutter speed 1.60th or higher and your ISO is probably going to be high too.
Thanks for that great lesson, Greg! Cheers from Germany
@gregorycazillo cool, sounds good. i really like and appreciate the more technical side. i wont mention any names but those other videos were getting kinda hard to watch. sooner or later people need to learn the technical stuff. THANKS!
Greg thank you.... really appreciate your videos....
WOW Man Wow! That was a great video! Thank you so much, I never knew there was this much info in the histograms. Great analogy with the bucket of water!
Yes !!! Thanks a lot !!! I really wanted to understand histograms !THANKS A LOT GREG! YOU ROCK !!!
@lopezae33 As I said in the video this will probably end up being a series on the histogram
thanks for this vid greg! new stuff to me: 1/2 of detail info is on the right!! maybe a secound vid about histogram should be how to work with histogram in processing (lightroome etc.)
In the digital world, the colors are represented by numbers - ex. typical 8 bit image has color value of 0 - 255. Histogram just quantize the, and shows how many colors used in line graph. So if you have a pixel having color value of 10 (pretty close to black, but not exactly pure black) and under expose it by color value of 20, this value would end up in negative zone (-10) and computer has to map this value to 0, hence you've lost some details by under exposing. Same is true for over expose
@dstubbso Not really, unless thats how you like your images. Its best to try and nail your exposure as best you can.
@piccicacca Sorry I don't know, I never changed it on my cameras its at default.
great video. Now I need to practice and understand the impact of adjustments. thx
Greg, you are the best!! Thank you very much!
Greg this was a top notch video.
Thanks.
thanks for the great informative videos. very helpful indeed.
Gregory, well done, thanks heaps.
