Have you ever fiddled with layer blending options? No? well you should!!
If you want to progress with manipulations, you should really definitly fiddle with this function. http://img.photobucket.com/albums/v321/ ... rs/lbo.jpg see where Ive circled on this picture, thats where the layer blenidng options are.
Take a regular picture and put this image on a layer above that image.
If you fiddle with the layer blending options
you can get a range of effects
much better than just changing the opacity on the above layer eh
I was going to write a tutorial but I'm actually in class now
, so I have to get back to work
