I was cruising Twitter this morning and noticed that someone I follow tweeted, "Your confidence with a model will translate to their confidence in themselves which will translate into better photos."
Good simple advice!
Ever notice how, when you're around a dog, and if you're acting nervous or lacking confidence being around that dog, it might effect the dog's behavior? It might get you snarled at or, worse, get you bit! Same with models. (Not that I'm comparing models to dogs. Dogs are often easier to train. Just sayin.)
