Face and Body Scanning / Choosing a single camera for photogrammetry
« on: September 01, 2020, 01:21:23 PM »
Hello!
I mean... this is FAQ, but still... maybe I could ask some questions and elaborate a bit more this subject,
since I didn't find an answer to my questions.
So. I'm currently planning a single camera "rig" for product scanning. It will be controlled studio light setup,
camera will be on a tripod and product is on the turntable. At least this is the initial plan.
Now I'm thinking what kind of camera and lens I should get in order to get the best quality out of the scans.
As far as I'm concerned, it would be the best if ISO is on the lowest setting, like 100 or something and lens f-stop is the highest
to reduce dof blur. So I should balance it out with light/lumens and shutter speed.
I'm thinking the lens should be 50mm fix, possibly
And the camera. I don't know yet...
Maybe something from Sony?
Like a6000 or going full frame and Sony a7 II or going full crazy and take Sony a7 IV
Price difference between these three cameras are about 3000 dollars/euros, hence the main question:
does the extra investment yield in better results?
Crop sensor vs full frame, 24 megapixels vs whopping 61 megapixels on a7 IV full frame?
Or maybe DSLR?
If there is any other factor I should consider, I'm all ears.
Thanks for the help!
