ask a pro if you can assist them at a wedding shoot some day. You know, carry their equiptment, move lighting around etc. but explain, that by being his/her assistant, you want to be paid in advice/guidance rather than in money. Have them tell you what they are trying to do with every picture, and what they look for. write down gear info etc. you'll learn a lot from someone professional. they should be nice enough to tell you what you need to know if you aren't asking for money. Photography is a pretty unifying hobby, if they see that you are interested, they'll be happy to know that they took part in you being able to turn out great pictures in the future. Every "camera person" I've talked to seems real nice, and happy that I am so young and interested in photography, enough where they gladly help.
