I totally get that! I used to be camera shy but my husband makes people feel so good about themselves when he's behind the camera, the shyness doesn't usually last. We start super slow, talk in the days leading up to it about what things you like and don't about your body, what you hope to see etc, then we talk a lot before and during (unless you are totally into it and want us to just be a fly on the wall ) making folks feel really comfortable. Once people see a little of how amazing they can look with good cameras/lighting/angles they really get into it. It ends up being super fun for everyone. Also knowing you don't ever have to show it to anyone but each other takes a lot of the stress away.
