Hi GiladAv, funny you should mention that, I have a project myself that needs the same functionality and will be having a stab at it next week. If you mail me I can share my results with you :O) Basic strategy will be to compare the "white" sample from the image, with true white, and apply the difference to the whole image. No idea if that's what cameras do, but it's a place to start...

Mr Peter Strømberg hello,

There is one filter I'm trying to create with the Pixel Bender, without no success,
it is Automatic White Balance.
Perhaps you have any algorithm or and knowledge regarding this issue.
any help will be appreciated.

thank you
