I have a grey 16 bit image with a limited range of values. Using cinepaint It shows up dark on my display. I'm guessing that what I need is some kind of display profile that will map my image values to something with a wider range.
ArgyllCMS is primarily about color management. You've only got color management when color spaces are known, and turning unknown device color spaces into known colorspaces is what profiling is about. So if all you've got is an unknown colorspace grey image, you either need to establish scientifically what color space it is in, as well as having a color managed setup to then evaluate and manipulate it, or give up on color management for this file and simply adjust it until it "looks good" in your situation. Note that if you have a non-color managed environment, then you don't know how much of the appearance is due to the file, and how much is due to the display. In a color managed setup there are two profiles involved here, one for the image, and one for the display. Graeme Gill.
