What colour is this?

It has been a long time since I knew anything about gamma correction. When I learned what little I did, I had no use for the knowledge. Now that I’m looking at photos and trying to put them on my website I’ve had to go back and learn again about gamma correction.

Frustratingly I couldn’t find a short simple explanation as to the best way of dealing with gamma correction. The Accurate Image Manipulation website has a wealth of information, but nothing that would give a high level overview instead of low level technical.

To help me remember the essentials in future I’ve put together a brief quide for handling gamma corrections when editing photos. Using xgamma to set the system gamma correction to 2.3 has really made a huge difference to my photographs, and mostly for the positive (there are a few that actually looked better darker!).
