So I have been wanting to improve my picture taking. However the only pictures I have done are nature shots and nature closeups. I really don't have a clue on how to take good pictures of people or street shots or anything man-made. Its not the technical aspects I cannot get but the seeing the shot. Maybe its because I have always been focused in on nature but I would really like to expand my view and how I look at these other scenes. So kinda a really abstract question but do folks out there have any pointers to try and help see the picture opportunities in non-nature pictures? I can't really go out and just shoot.. I don't think like that. Even with digital I still like to have the shot in my head before clicking the shutter but with urban or people I can never really seem to get the shot to appear in my head.
