Escorts usually suck because their mere presence often competes with the authority of the photographer. They can also get in the way of chemistry between the photographer and subject.
Here's a few tricks I've learned when dealing with escorts.
#1 - Reverse Psychology
Do NOT make a rule against escorts because that immediately draws suspicion from talent. SO instead....go "Yeah, escorts are great! I love escorts because there are so many creeps in the industry and a girl should always be careful...so yeah, I'm totally cool with escorts and I'm really glad that you are concerned about safety." Be really sincere when you say this...and half of the time...the model will leave her escort at home just because you didn't sound creepy when asked.... Try it...reverse psychology works
#2 - Bore them to death
Photo shoots are boring as hell for everybody that is not directly involved in the shoot. It only takes 20-30 minutes of sitting around watching the set until escorts get really bored. This is a good time to give them an escape-hatch, ejector-seat or basically an excuse to do something else. Make certain to have something for them to do that is away from the photo set. A couch and a TV set in another room is perfect. I had a big screen tv, dvd player, tons of movies, big fat red leather couch in my previous studio that was a perfect place for escorts to take a 2-4 hour nap and leave me the F alone. Other things work too....be creative...cigarette runs...alcohol runs....pizza runs etc
#3 - Put them to work
Ask the escort to hold reflectors, move lights, hold flags and other monkey work. This can have one of two effects. First, it can actually help you! Wow, what a concept! Some escorts make excellent assistants. This also submits them a little bit to your authority so that the photographer becomes dominant and stays in charge of the photo shoot. Second, some people hate to work and will immediately make excuses to get out of it. The best excuse is when they want to go home and then come back and pick the talent up later. "um, I forgot that I've gotta run some errands....can ya give me a call on the cell when the shoot is done and I'll pick ya up later?" PERFECT...escort just dismissed himself
damn...this post is making me seriously think what a devious bastard I have become over the years. But anyway, just a few ideas that may help somebody out...maybe
