Thanks Steven for these videos, we now have more informations about how RC handles the raw files - so I even suppose that RC is actually relying on the installed driver : it may be possible that we have different results with another set of codec installed. But to be sure, maybe this is better to stick to JPGs (or TIFFs, I know they are huge, but maybe with fast drives it could speed up the image readings ?) generated outside RC.
About PNGs, according to my tests on features-rich images (the images that we love in photogrammetry), you do not save much space (comparing to TIFFs), so I don’t think this is worth it.
About the 5500K white balance for all shoots, I eventually came to the same conclusion (my conclusion was : instead of measuring white balance or switching between sunny, cloudy and shadows preset (and make editing complicated after), let’s stay on the middle preset (cloudy) that should be a all-around preset for most cases). Actually I think that depending on the body, 5500k is in between “sunny” and “cloudy”… I will test 5500K for my next capture, thanks for the information ! Of course I think that does not prevent us to get some color checkers, just in case…
We could also try to capture the color temperature coming / white balance from all directions with a sphere diffuse gray probe I guess for large environments captures. Anybody has some experience of this ? This could then be used, after a first alignment, to process the raw pictures (using the xmp datas that contain images orientations)… how does it sounds ?
