“If you use static light you will get shadows” I think I understand - you mean shadows all from same direction?
- Yes, with static tripod-umbrella-type flashlight you will get static shadows. We don’t want static shadows.
If you use mobile light you will get texture mixed from different pictures and shadowed parts on one picture will mixed with illuminated part from another picture. Finally you will get uniformly illuminated texture." You mean still shadows. but any given object shadowed from a different direction in each of the overlapping shots? I can see that a bit of shadow must help with flat nearly smooth surfaces like plaster, esp finely textured like paint brush marks on plaster.
- Nothing will help you with flat\untextured surfaces. It will be reconstructed very bad. You must correct it in postprocessing - pretexturing workflow. I use Geomagic Wrap for this work. After I get mesh from RC I correct it in Geomagic and then return to RC for texturing.
“You must capture in RAW and then correct shadows in Lightroom\Capture One.” I thought that kind of messing with image was not liked by RC - or is that just about optical messing, like cropping or distortion removal?
- You can use postprocessing of RAW, but carefully. No cropping, No undistortion. Just make your picture uniformly lighted and correct colors, uniform it. I use ColorChecker Passport.
In general, I thought there’s a danger that RC may mistake a shadow for a feature, esp getting confused if that ‘feature’ seems to move.
- No. This technology is not depending on shadows. It’s more complicated. Surfaces must be textured well, your shots must be excellent quality and all will be fine.
