sRGB internal processing and bit depth

[hajes29a]

Thanks for reply,

if I understand correctly ICC profiles only shows how it looks like and doesn't alter any data in source file.

I usually import TIFF, 16b because my camera has got real 14b DAC.

I let most setting default in GIMP so it is imported in 16b linear and built-in sRGB

Exporting JPEG, sRGB, Q100 for printing since not all labs take TIFF 16b and because there is no printer capable of 16b color depth anyway
