WebDec 1, 2013 · Light in the real world is linear. If you triple 100 photons, you then have 300 photons. But the human eye does not see a trippling, we see only a modest increast by comparison. This is in part why transfer curves or "gamma" is used, to make the most of the available code space in an 8 bit image (oversimplification on my part I know).

WebIf there is, convert to sRGB. That remaps the tone curve and there won't be any visual change. If there isn't, this is getting a bit more tricky. Then you first need to find a linear gamma profile with the right primaries and white point, and assign that. Then you can convert to sRGB.
