I do not claim to be a pro, but friends trust me to shoot their weddings. At the, hopefully very last wedding that I shot, I insisted on finishing each formal shot, and then I let everyone jump in with everything from cell phones to some fairly expensive prosumer cameras. The were all amazed that my photos "came out better" than theirs. I had been testing shots over a two week period to make sure that I got the lighting correct. It was a tough mixture of tungsten, flourescent, some bright unknown, & varying strength of daylight. Then, for each location, the WB varied greatly.
No matter how much they say they just want some snaps to remember the event, their expectations after the fact are much higher. "Why does she look so much better than I do?", etc., etc. The problem today is those holding up their iPads during the ceremony. Yikes!
