Kit, I have Photoshop Elements 3.0, which is now well out of date (I think they're up to 8.0) but does what I want. No paper manual with it when I got it but onscreen help. However there are useful books such as Photoshop for Dummies, and many others, which are helpful. It has lots of functions I never use. I mostly use sharpening, which tidies up the pixels a bit, levels to play around with the contrast, and maybe adjusting the colour here and there; plus spinning it if I haven't got it quite straight (happens a lot with these lightweight cameras) and cropping it to improve the framing. And the clone tool is very useful - you can copy something you like, as small as one pixel, to somewhere else, which has more uses than you would think.
