This is also incorrect and trivializing of the color science. Images may use gamma correction, they may not. Trying to describe it in terms of gamma is like trying to describe food in terms of saltiness alone. You're ignoring tons of other factors.

[mark-r]

Any image being displayed, or encoded in a standard such as sRGB, is using gamma. It is not optional.

[lmm]

Sure, and any meal you eat will have a salt content (possibly zero). Doesn't mean that that tells you all the things that could be wrong or right about the meal.

[ElephantsMyAnus]

No. It isn't there so that you can use it when you choose to. All devices expect it to be used. When you skip it the colors will be wrong.

[dagmx]

You're missing the point. You can't ONLY describe color spaces in gamma differences.

Gamma is just a single element of a color space. The whole trivializing sRGB into being a 2.2 Gamma versus linear is an over simplification that ignores gamut , white point, bit depth and more.

That's my point. You're trivializing what color is because you clearly have not dealt with it at scale.

[ElephantsMyAnus]

No I'm not doing that, there seems to be some problem specifically there. Either the values are converted incorrectly, or not at all, effectivelly stretching about 8 fstops into the 11.6 (slightly less for video) f-stops of sRGB.

You can download an alternate color scheme from Technicolor for Canon cameras that makes the colors appear fairly reasonable.

[dagmx]

"makes the colors appear fairly reasonable"

From what color space to what color space, and what display or print type?

Now you're back to describing a average case perceptual color rather than your initial point of accuracy.

[dagmx]

I meant using gamma as a conversion function. There's a whole world of color transformations outside of just gamma. Gamma is just one of many transformations, and you can have two color spaces with identical gamma transforms, but different gamuts, white points etc...

[mark-r]

I think a lot of people were misunderstanding my comment. I never meant to imply that gamma is the only important consideration in color perception, I was only reacting to the statement that it was optional. Even color spaces that don't use gamma (i.e. are linear) must have a gamma applied before you can view them.
