I would like to know how to draw a gradient background between two colors. I
have successfully done this with blue and black but I don't seem to get it
to work with blue and red.
Is it possible to apply certain filters with a gradual severeness in different
parts of the picture. I was thinking of restoring photographs taken with a
flash that are very bright in part and dark in another part.
If brightness could be applied with different weight in different parts of the
picture it would make my task easy.
Is this easily done?
