Adobe Photoshop may be horribly expensive, but it's the best image editing package on the market, bar none. There's virtually nothing it can't do, as long as you know how to use the software.

This is an image of the waterfront at Kingsand, Cornwall. Well actually it's two images that I stitched together in Photoshop: what a clever package that is. 
I'd be happy to share some Photoshop tips/techniques here if anyone's interested? The £600.00 UK price-tag is prohibitive, but there are loads of people wearing eye-patches out there! 
Thats the thing though - its really complex to use as well as costly. I'd love to have a go, but I find I can do 80% of what I want in Paintshop Pro..
Great pic though - I dont think PSP could do as good a job!!
