My son asked me to shoot his coming wedding as the primary photographer. Not because he can't afford it. But because he said he trusts me to do it right. I declined, but told him I would shoot as well. He's happy with that. I'm not ready for something like that. Plus, I don't want to ruin what's supposed to be a special time.
Exactly what happened to me last year. I had both of my sons married 5 months apart. First wedding they asked me just to do some candid shots and the pro would do the bulk of the wedding. She seemed nice, and showed me her D800. She asked what I was shooting with. Oh. D5100? Sorry, she says, I gave up toys years ago and moved on to a "real" camera. Bitch......
Second wedding was some guy with a Canon. Refused to talk. Ok, fine. I took my shots, and he took his. Near the end, they were taking some outside shots, and he was clearly having a problem with his equipment. It had been raining, and it cleared just briefly to take a shot with a nice pink sky. I just had it on full Auto and pulled off only 3 shots while he fiddled with his camera. Clouds closed up the sky, and he never got the shot. They ended up using mine for the newspaper announcement. He even called my son to ask why HIS picture wasn't used for the newspaper. His pictures we just ok, not much better than mine.
I've been asked to do a few small weddings and parties. No thank you. This is only a hobby for me. Once it becomes a job, the thrill is gone.
