I am relatively new to RawTherapee and have a question about the ‘Tiff 32 Bit Float’ export option.
My plan is to work on the RAW files of bracketed photos in RawTherapee and later stitch them together to a 360° HDR using PTGui.
So I adjust the White Balance and remove Chromatic Aberration on one photo in RawTherapee, copy-paste the changes onto every photo that I need for the brackets and export every photo as an uncompressed 32 Bit Float TIFF.
I stitch them together in PTGui and everything seemed fine but when ich checked for the highlights in the HDR I noticed that the bit depth of the originals was pretty much gone.
Does the uncompressed TIFF Export reduce bit depth even if I select 32 Bit Float Export?
I tried again to work with the original RAW files in PTGui and then everything worked fine, so I’m definitely doing something wrong in RawTherapee.
Thanks a lot for your help!
