Quick question , if you wanted to give the effect on a photo, of a rainbow type light effect running diagonal ie top left to bottom right,,any idea how too using cs3...
easiest would probably be find an image of a Rainbow on the net save the image to your PC and using the layers put it on top of your photo, then change the opacity of the rainbow image till you get the effect you want.
Not sure if it's what you're after but you can get some interesting effects playing around with 'Lens Flare / 'Lighting Effects' (under Filter - Render - )
Layer then gradient tool was the way to go......did try the lighting effects first time round but could,nt get the colours correct, thanks lads all done.
