Many thanks for the kind welcomes and the generous advice.

Hi, I've just discovered this forum. I've been a Pentax K1000 user since I was 18, 25 years ago! Last year I bought a K10D, which I'm delighted with, as it has revived my interest in photography. I use Photoshop Elements 6, but my colour blindness limits the editing I'm prepared to do.

I'm currently thinking of buying a flash unit, so any advice would be welcome.
