1 year ago I think you should ask your first question on the libraw forums first since you were able to reproduce the issue with dcraw directly.
Regarding your last question, what exif data does dcraw write?
Hi. I have issues with using custom output profile with both dcraw and libraw. For some reason I get sRGB all the time.
Command: $ dcraw -v -6 -T -o AdobeRGB.icm RAW_SONY_A7RIV.ARW Loading Sony ILCE-7RM4 image from RAW_SONY_A7RIV.ARW ... Scaling with darkness 512, saturation 16383, and multipliers 2.776046 1.000000 1.278800 1.000000 AHD interpolation... Converting to sRGB colorspace... Writing data to RAW_SONY_A7RIV.tiff ...
My sample image and profiles: https://drive.google.com/drive/folders/1Ga_iukvQIz8SZJgumPzper1BBNqxLd7A?usp=sharing
I did modify rawpy (https://github.com/letmaik/rawpy) which is a wrapper library for libraw to pass output, here is the diff: https://github.com/letmaik/rawpy/compare/main...kamikaze:rawpy:feature/profile-params
Does anybody have any example on how to get RAW image data converted and saved into the file with a custom profile? Thanks
Also is it possible to use dcp camera profile ? I'm not sure it is working for me, but idk if it should.
And the last one: postprocess returns just a NumPy array w/o any data. How can I write the file with exif like dcraw does?
