What camera is best for photoscanning? Is my mobile phone ok for capturing 3d scans? Should I buy a DSLR? In this video we'll talk about 3 parameters of any capturing device that make a difference in photoscanning quality.

What camera do you use for photoscanning? Is it a dslr, a mirrorless, a smartphone camera? Leave a comment! :)
p.s. Throughout the course, we were using Canon 80D with Sigma 17-55mm f/2.8 and Sony A7III Tamron 28-75mm f/2.8, and the whole range of test devices: OnePlus 6t pro, Sony XTIV, Canon 550D, etc.
Using a Samsung Galaxy Note 10 plus. The overall sharpness and fidelity is good, especially with the Pro mode, but it underperforms in low light conditions (eg:indoors) and the results have a lot of motion motion blur or noise, like you explained.
Using RealityCapture gives better results than meshroom in my case.
I've been using a Sony A58 :) Been working out pretty good so far!
Canon SX120IS пока хватает.
"Resolution", "Spatial fidelity", "Raw sensor data" , а так же то, какой камерой делается съемка не имеют никакого значения если снимать прозрачные, бликующие и однотонные поверхности - результат всегда будет плохой и нужно использовать уже сканирование лазером.
НО есть выход иногда - на снимаемый объект (либо его неудобную часть) можно нанести/напылить "краску" чтоб поверхность была не бликовая и не монотонная , а была близка по виду как гранит - зернистая. А текстуру можно получить на объекте например проецированием фото на модель либо каким-другим удобным способом.
Fuji X-M1, the same camera since 2015. Good resolution, cheap and lightweight. Unfortunately, not sell anymore.
Mostly Sony A6400 (24mpix APSC) with tamron 17-70 f2.8. Killer combo when it comes to price/quality.
Sometimes when I don't have the camera on me I just use my phone with Reality Scan app.
Your content is comparable to gold! Real glad I found you here on CZcams, thank you Gleb!!
Awesome video, thanks! ❤
interesting graphic on the wall at 5:04
Didn't know that Gleb was into street art XD
С Новым годом!
Finally some quality comparisons and a quality video that goes at least a tiny little bit into the technical details of photogrammetry. Most videos/creators don't do that.
Thanks. Yeah it's possible to go deeper than that, yet the notion of spatial fidelity gives at least some sort of reference frame within which different capturing devices can be evaluated.
Привет.
Спасибо за видос. С зарплаты подумаю о том, чтобы купить твой курс по этой теме, т.к. подача на уровне)) Будь здоров и удачи;)
Great video (as always) I wonder, which phone scanning app would you recommend? Specifically for ios...
Could you please link some cameras & lenses that are on the mid expensive range? would help very much
Хорошо бы затронуть вопросы сравнения в использовании DSLR камер для фотограметрии с электронным и механическим затворами. А еще инетересна тема использования промышленных компактных камер с сменой оптикой.
Nicht nur das, sondern auch wie hier in dem Video, was denn die Kameras kosten in dem Beispiel. Und was man mindestens ausgeben sollte.
if price was not a factor, which DSLR/ lens would you recommend for capturing plates of food. So pretty close up in general. Would like to get the most realistic models possible.
Hi Eric, feel free to ask in our Discord community - there are photoscanning pros there who would definitely know what lens to recommend for such work :) discord.gg/nNReRkzWsh
Is it available yet? Will the software be included with the course? Is it going to be expensive am on a budget.
Hi Raymond, yes it's available on Blender Market and Gumroad:

What about a "high-end" phone? Let's say an iPhone 13 or Android equivalent? Are the results comparable to DSLR or are they just slightly better than midrange smartphone?
P.S. Thanks for the amazing info in the video!
Smartphones have a lot of enhancement filters automatically activated. The main difference between a mid-range smartphone and the iPhone is the quality of these filters. The raw files are not as good as DSLRs due to the sensor size and lens quality.
There is a datasample set for the "Reality Capture Gingerbread man".
The pictures are captured with a Galaxy A71 smartphone.
It's all about the quality of the raw data. They just used ISO 36. What helps is the wide DOF on these small lenses.
For macro shot photogrammetry, say insects (museums do these extensively), Focusstacking is used to get a very sharp picture at every camera position.
Guys im between 42 mp a7r2 and a7r 36mp.Please helb.
Mind sharing what affordable DSLR you used :)
Oh we used so many different cameras, starting back more than 10 years ago with some really cheap $100-200 compacts, then moving to dslrs (Canon 550d, then a mid-range crop-sensor Canon 80D and so on), then Sony a7iii which is in a full-frame league, but bought used. We photoscanned using smartphones as well, so I guess it boils down to following the best practices of photogrammetry and getting most out of the equipment you have. :)
Define affordable. Nowadays cameras are so good that even a camera from 4-5 years ago can produce excellent photos. Probably the best choice would be to go back to several generations before to find something really affordable.
@@paweljankiewicz1383 I definitely second that, the best bet would be to search among the 4-5 years old cameras, there are amazing higher-end options in this segment which became, like, 10 times cheaper over this period (well, I'm exaggerating it a bit, but not too much).
I have a hunch that Micro Four Thirds is best for Photo scanning, Why? I think I'll make a video about it ;)
Probably because you need to close the aperture anyway, slightly more on the fullframe cameras, slightly less on the MFT sensors, but it has to be closed, so why pay more :D right?
@@GlebAlexandrov don’t forget about the IBIS: far better on MFT, easier to get sharp shots, even if the shutter is slower.
My GH5 is showing a lot of noise when making photo's so I'm buying a full frame Lumix to make photos scans
Canon 5DS r
When does the sale end?
In January, most likely - once it's feature complete (we're still adding some videos and even chapters).
Rent cameras with different specifications and test them, you should be able to draw the best conclusions.
Good idea!
if you own a smartphone with a lidar sensor, just use that
As an option, sure, why not.
Big thanks @gleb I was actually looking for it. Stop reading our minds )))
I thought it's a pretty off-topic video for our 3d Shrimps, but at the same time I *know* that this question is in the minds of pretty much everyone wanting to do some photoscanning. And while I don't want to give concrete recommendations, I think it's still important to understand the principles of choosing the capturing device (aside from the budget :) )
