I’ve taking about 50 pictures of the Orion nebula, each exposure 20 seconds long at base iso. It’s only a 135mm lens so there is nothing exceptional but it’s the best I can do. I intend to stack them using another program, but this program needs tif files as input.
Rawtherapee easily batch convert my rawfiles to tifs, no problem there, but the question is if there is any thing I should do, or not do to preserve every little bit of information that might hide in the dark parts of the rawfiles. For instance color temperature, is daylight usually the best as to not cut/push any information out? Should I move the black point? Colorspace?
Any hints appreciated.
Edit, after posting this I saw the “Save unclipped images” post, that might just be what I was asking for…
