Dear Craig, A stupid question is one that is better answered by a moment's thought or a few minutes' experiment, rather than asking on a photo forum. It may also be one to which there is no answer, such as "will I like Canon or Nikon better". Sure, there's no fixed point. I didn't intend to suggest there was. Quite often, I'll be quite patient if I think I can help someone. But if I don't think they can be helped by anyone, because they don't want to hear the answers, or will ignore them no matter what they are, or just want their prejudices confirmed, I'll tell 'em to go and take some bloody pictures. That's where I draw the line. Where do you draw it? Cheers, R.
