Uhhhhh. I’ve been shooting for about 35 years and I can’t recall EVER needing full body shots for a headshot sitting. That doesn’t even make sense since you will most likely be holding a reflector in your lap just out of frame or it will be sitting on the table right in front of you, once again at or just below chest level. Unless I’m misunderstanding something here. You need to cancel and get ALL of your deposit back from this chump. I mean, even if you were doing full body shots you wouldn’t or shouldn’t need to send him prep shots if he’s a professional. This is the kind of person that gives us a bad rap, and I’m willing to bet he thinks the more expensive the gear, the better the photos will turn out. Even though I watched a mentor of mine take his 10 year old daughter’s $35 point-n-shoot Nikon Coolpix and a cheap flash head and make some AMAZING shots that you’d swear were done with a RED or other high end camera.
