I have ben using PS for a number of years now and have upgraded along the way to CS3. It is all I need, but it is damned expensive to buy outright.
Elements 6, on my other computer, looks a bit 'basic' after CS3, but probably does a good job. I haven't bothered to use it much though.
I got a copy of Adobe Photoshop Album Strater Edition 3.2 free somewhere along the way, which is a catalogue tool and downloader. I do not use this perhaps as much as I should. I have never heard it mentioned here, does anyone else have this?
