@Aaron: I know! I was kicking myself as I reckon I could've gotten a sharper shot...
I've now started to use any surface I can find now to steady my hands - place the camera against a wall etc. I know this won't always work - but it'll definitely come in handy. (I'm not really a fan of the tripod. It has it's place, I guess. But I can't lug it around with me all the time. And it'll probably take away the "candidness" I tend to love).
@Zahra: Thanks, I messed around with the saturation/curves abit to enhance his coat.
@Duncan: Dunno. I may yet see if I can dig sort something out.
