I know we disagree, but I think you control what you can, when you can. Then you have to take what you get. I couldn't ask the man to stop cause he wasn't posing for pictures..
I doubt those photo journalist in irag are too concerned about exact framing when they are in a firefight. If you are shooting a general passing out purple hearts in the hospital, yeah they do try to control everything. More than any wedding I ever saw as a matter of fact. I have never been to Iraq but I saw how it worked in Asia when I was a kid.
It works like that for me in a wedding situation. If you are posing people on the pretty bridge there probably isn't a lot of excuses. If you are shooting picture from the balcony during the ceremony, you take what you can get.
If you are shooting pictures of the bride and groome cutting the cake, then yeah you dont have much excuse for a piece of decoration crossing their head, but if you are shooting mom and dad dancing and just when you take your shot a hand gets on the back of his jacket, and the dance is over, I personally don't ask them to pose for me again. It's called candids.
Here again I know we see things differently but thats how I see it, and you see it your way. There is nothing wrong with disagreements at all.
