Find out gamma setting
show user profile  zeefusion
I have been sent some textures that I have been told have not been gamma corrected and were kept linear. How would I find out if this is true?

Is there a way of finding out if the image is corrected or not? When I right click the JPEG and go to details it says the color representation is uncalibrated.

I then viewed the details of a normal JPEG that I believe to be gamma corrected from a digital camera. The color representation says sRGB which is gamma 2.2.

Jpegs are almost always corrected. If it looks ok to your eyes, anyway, then there is no need of correction.
If you are unsure, ask the one who sent you the image if it's looking ok as he or she sees it on screen.
If it's too dark, roughly speaking, than it's not corrected. If it's ok, no problem.
Anyway, srgb space means 2,2 gamma, which is a burnt in calibration of midtones of the image.

The person is unsure if it has been gamma corrected also. It is a bit up in the air at the moment. As you have mentioned my assumption was that if it is JPEG then its most likely gamma 2.2.

But can you not save JPEG from a digital camera with no gamma correction?

doesn't matter if it's been corrected or not, gamma'd up or down, fucked sideways or missionary.


does it look right?



yes or no.

It looks right, I think there is some confusion with matching the photo on a colour corrected monitor to a real life sample. I guess on a colour corrected monitor at gamma 2.2 it would be the same as viewing it in real life?
