Good Idea Peter. I agree, I was surprised to see what could be done with my original image! I thought I must have been doing something dreadfully wrong when capturing the subs! Turns out it was just my dodgy processing
I did have a quick go with it i photoshop after PI. I'll have to have a read up on adding layers, not too sure how to do that.
Thank's for all the help in steering me in the right direction.
