I will e-mail the name to you.

Thanks,

Legally none, since they have no authority over you and don't "own" anything which happens in public at the event. In practice, if videotaping something appears likely to cause the photographer to create a scene then either try to find a creative way around that or notify the couple and move on. I had a photographer several years ago who told me to get lost while she was shooting her formals, so I just moved further away and kept shooting from a distance. In hindsight I can understand why some photographers don't want other cameras around because it tends to distract the subjects, but seeking a reasonable compromise is the professional solution for all concerned.

Catch this line
 

Here is a nifty line from his photo gallery.....

Derek Pye is generally acknowledged to be the greatest wedding photographer in the world

Yes it is parody, and it is still funny. Except for the comments below that post. A bit unnerving.

Wow....
 

I loved the part where the photographer trips over the metal bucket / can on the concrete and everyone turns around.

I have to wonder why they didn't just stay put since there were so many of them. Just like any other production you have your assigned area and you stay there.
