Hi Andy, I still prefer the black and white version! As I said in the other thread, maybe this is because I saw the black and white version first, so the colour version appears like "colourised" b&w to me! It could also be because I've been shooting black and white film all year (apart from two just recently).
A reasonable question for a film photographer to ask of a potential image is: "does it need to be in colour?". I realise this question is a bit redundant for digerati as you get it in colour whether you like it or not (unless you choose to shoot b&w JPEG with no Raw, which AFAIK few do). But I think it's good to think about that before pressing the shutter, rather than later when sitting in front of the screen. Not to say I haven't done the second thing, though!
Mind you, there are two more questions I should be asking: "does it need to be in black and white?" and, if the answer to both those is no, "does it need to be shot at all?". I'm not yet sure whether there are interesting images where the answers are no, no and yes!
