Hi Paul, although I've ordered the new gear, I'd be foolish to decline your offer of advice. You were most helpful when I first got my Sigma lens back in March 2006!
Here are a few of my best images. I put them through Noiseware Community noise-reducing software then gave them basic tweaks (contrast, brightness, saturation, sharpening) on Photofiltre. It's not that I'm not happy with them, but I believe (recklessly?) that the Canon equipment will do better.
What free or cheapish processing software would you recommend? Or is it worth getting hold of, say, Photoshop Elements 5, a used, as new copy of which can be bought on Amazon for under £15?
Thanks in advance.
