H4rri and Sophphoto,thanks for your comments,H,I only have the software that came with the camera so its pretty basic and limited.I try not to tweak a picture too much,if a picture has not got any basic attributes,I ditch it.Rightly or wrongly,I have always believed that you dont learn from dwelling on your mistakes ,as much as you do from what you do well.I've got a lot to learn.
