From a photographer’s point of view I totally agree, there’s nothing worse then some cocky guest trying to compete with you for the couples attention when your in the middle of doing the formal pics.
Cameras I don’t mind as much but people with cameras on their mobile phones pisses me off for some reason particularly when they walk in front of the official photographer so they can get a better angle, I mean LOL, why would u even do that, you are ruining the couples official photographs and when the moment has passed it’s passed.
I am not sure if this no camera thing will catch on however I’m not totally convinced if this would stop people’s pics from going online. I have photographed some mendhi’s where the family had asked the Dj to make an announcement that they would like all the guests not to film or take pics when the dancing has started so these images are not abused, this i thought was a great idea.
