Johan Novak blogged last week about gamma correction: What Every Coder Should Know About Gamma.

What I thought:

Gamma is a relic from the CRT display era; now that almost everyone uses LCDs, it’s safe to ignore it.

Turns out I was wrong.

Don’t feel bad if you have answered most with a yes! I would have given a yes to most of these questions a week ago myself too. Somehow, the topic of gamma is just under most computer users’ radar (including programmers writing commercial graphics software!), to the extent that most graphics libraries, image viewers, photo editors and drawing software of today still don’t get gamma right and produce incorrect results.

So keep on reading, and by the end of this article you’ll be more knowledgeable about gamma than the vast majority of programmers!

Don’t know about that “vast majority” (I hope we are not that hopeless), but I do recommend reading the rest.
