Thumbnails not correctly rendered from 32 bits FP TIFF images #4118

Open sguyader opened 7 years ago

I saved an HDR image from bracketed shots in LuminanceHDR (output as 32 bits per sample, floating point), to further process it in RT. In RT's film strip or file Browser, the thumbnail of the HDR file is always much darker than the file opened in the Editor. See screenshot below: TIFF opened in Editor, corresponding thumbnail in the strip above, 5th starting from the left. screenshot_2017-09-29_08-52-08

I haven't found this issue reported already (or I searched with the wrong keywords) so I opened this issue.

IIRC the files from LHDR lack ICC profiles.Try assigning RT_sRGB as the input profile and see if that helps.

sguyader commented 7 years ago

Indeed it's a matter of input profile. By default RT opens the file with "Use embedded, if possible" as input profile. If I set the input profile to either "No profile" or "Custom", then the thumbnail reflects what is seen in the Editor view.

Maybe this will be handled during the unification of the pipelines.

Can we close this old issue?

@sguyader it's still a valid issue, isn't it?
