How do you become a really great photographer?my brother's gf takes some really great pics

you just take a lot of pictures... eventually you just develop sort of an eye for it... you can just look around and see what would make a great shot...

With lots of practice. I take pics of old cars when I go on vacation. It is a pain when people stand in in the f***ing way when your trying to take a pic.

Some people have a good eye and it comes naturally. My mother in law could take fab pics with throw away cameras. You could give my aunt the world's best camera, she was terrible. A decent camera is a good idea and lots of practice. I like the digital because I don't waste film, so it's good for practice. My best pics still come from my 35 mm, but it usually doesn't matter. Practice, practice, practice.
