Just another short story. My first wedding photo booth. Not a difficult thing to do but I wanted to be prepared. I learned about the inverse square law because after people have a few drinks it gets goofy and people don't line up. Sometimes they are 3- 4 deep and I did not want to nuke the ones in the front and underexpose the ones in the back.
I asked a few questions at Fred Miranda and got a hard time about it but I did not care. I figured out the minimal distance to the flash to evenly light all the people, put red tape across the floor and made sure no one crossed it. Easiest money I ever made and everything went great. I think photographers are underpaid for weddings and overpaid for this type of stuff I guess that is were it balances out.
I my not be a pro but I need to be mentally prepared when I head into an important event, especially the first time. The chances of something going wrong exists and you need to react quickly to it.
