Unlike the original poster, my images don't become JPG until the
final production panorama is converted from 48-bit TIFF using
RawTherapee or LuminanceHDR. I shoot raw format in the camera, so
there's no JPG at all during processing.Could you explain your workflow a bit
more? What is between RAW and
Hugin? RawTherapee I suppose, but what "profile" do you use? And what
exactly TIFF->JPEG "converter" does? Does it do e.g. tone mapping?
Tonemapping. My RAW and TIFF images are 16-bit per color (RGB). JPG has
only 8-bits per color. Every time you convert from 16-bit to 8-bit, you
lose color information. That's why, for instance, you can adjust
exposure on 48-bit TIFFs but not in JPGs.
Anyway, I think the original poster's question boiled down to "Why have
color profiles at all?" I found this on howtogeek, maybe it's helpful:
