There is no such thing as a professional wedding videographer
Fortunately most people realise that the photographer is the talent at a wedding and it's easy to get the video monkey moved from the best spot. Derek's Tip: If you're the photographer and you stroll up to the front and find a big clumsy tripod in the way, with a camera left running, it's a fun idea to nudge it slightly so it's filming the Vicars backside. This will in no way detract from the miserable, cliched, under edited waste of TV viewing time that you will receive about 6 months after your wedding. It will have taken so long because during the week he'll be doing his real job as a prison guard and won't have had time to finish it. When it does finally arrive you'll be amazed how even after ruthless editing he has managed to make the wedding appear 3 times as long as it really was. You'll laugh and marvel at the genius idea of interviewing the guests but wonder why he failed to get anything interesting out of them.
The worst is yet to come when you get your wedding photos back and realise that for some reason the videographer, with an uncanny knack for always being in the wrong place at the wrong time, is in ALL your pictures. Lurking around in the background of every key moment, creeping out the bridesmaids. At least you'll remember what a waste of money he was for the rest of your life.
