There are comments on this question suggesting that gamma is off topic due to it being on topic elsewhere. However, I think we need to decide what is on topic here, independently of what is on topic elsewhere.

Should questions about gamma be acceptable here?

  • $\begingroup$ @ChristianRau Definitely. I'm happy to see it on or off topic (I asked the question on main to prompt this discussion), as long as it's not off topic for that reason... $\endgroup$ Aug 5, 2015 at 19:54

1 Answer 1


I dont really understand how it could be possible for it to not be in scope. It is:

  • A graphics hardware related concept
  • A mathematical concept
  • A image data compression scheme
  • Related to producing and computing properly with image data
  • often needed for good quality physical shaders to be easy to implement
  • affects, filtering and signal procesing in images


ok so gamma may not be the last word in color correct workflows but still.

Ps: is compression a allowed topic?

    $\begingroup$ That last sentence sounds like another meta question, or even a prompt for a scope-exploring compression question on main... $\endgroup$ Aug 5, 2015 at 20:34

  • $\begingroup$ @ChristianRau you're right - I missed that one... $\endgroup$ Aug 5, 2015 at 20:50
