i really enjoy the photography hobby, and have a good working knowledge of the XTi i've had for about a year now. We went to hire a photographer for our wedding last year, shortly after I bought my camera. We didn't hire her, but she has been helping me with tips and giving me c&c on the photos I've shown her. She told me that she was very impressed by my progress, and that she's booked with weddings for the rest of the year. Any saturday I want, I can come down & help her with wedding photos. I wouldn't want to get paid, and any pics I took would be all hers - that's not an issue. question is - is it a worthwhile upgrade to sell my XTi and get the new 40D when it comes out? I'm not planning on photography ever being anything more than a hobby, although it may end up making me a few bucks sometime down the road.
