The following Wikipedia pages does not describe so many methods but are probably easier to start with: http://en.wikipedia.org/wiki/White_balance http://en.wikipedia.org/wiki/Color_temperature The following article is even less technical but is also a nice read and it explains the most common issues with automatic WB. http://www.cambridgeincolour.com/tutorials/white-balance.htm Anyways, a plug-in providing several WB methods would be cool but, in most cases, I believe that it would be even better to extend the Color Balance tool with the ability to manually pick the grey point in the image. The easiest way to implement that feature could be to add a 'Set White Point' button to the Color Picker tool. _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
