I had a funny one recently. I was at a wedding taking my pictures and my assistant was checking off the brides must have photo's as we went along. This particular bride had given us a 3 page typed list of must have shots. She was so sweet and just wanted to make sure everything was captured, but there were so many specific shots, it sort of reminded me of a scavenger hunt! Anyway, we got most of the way down the list and realized that we had overlooked one, "Groomsmen walking like Pat Rack". Hmmm, I felt really stupid, but I had no idea who Pat Rack was. My assistant googled Pat Rack on his phone, there's a clown named Pat Rack... did they want to walk like clowns? No. As it turns out, it was a typo, they wanted to walk like the Rat Pack, Frank Sinatra, Dean Martin... that made a lot more sense! And made for a good laugh.
After thinking about that day, I was thinking of ways to make a more effective list, so here you go:
1) Things like "the first dance", "the cake cutting", "bride and groom coming down isle" etc. are kind of obvious. AND, they just make it harder to pick out the ones that are things we may not have known to get, like you with Uncle Bob.
2) Try to keep your list to what is very important, leave some room for creativity from your photographer.
3) Review the list, make sure you didn't miss anyone and make sure you don't have your groomsmen walking like Pat Rack ;-)
