Hi!
A couple of years (+/-) ago, I used gimp to change a night photo into a
full blue one. I cannot remember how except that it was very simple.
I think I did something like decomposing the image into 3 images, each
one in its own color (red, green, and blue) and just picked the blue
one, but I am not sure. Now, I need to do the same for another photo and
I cannot do it. Everything I get is 3 gray images when I decompose into
RGB!
Any help?
