[Gimp-user] How to move the white point?

[Juhana Sadeharju]

Hello. How do I move the white point in GIMP? All three photos below
were taken with the camera. How could I reproduce the photo 3 from
photos 1 and 2 in GIMP? That is, assume I don't have the photo 3 below
but I want something close.

http://www.funet.fi/~kouhia/whitepoint2.jpg % wrong whitepoint, example white
http://www.funet.fi/~kouhia/whitepoint3.jpg % whitepoint based on example white

Hi.
Check out the levels tool. There is a grey point picker which allows you
to define a 'neutral' color and adjust the image 'automagically'.

cheers
