A person with a camera helps you pose. Heck, you can pose yourself a million times 'til you get that selfie juuust sooooo.
You KNOW your angles, right?
But maybe, just maybe...as a professional photographer...I can see you differently than you see yourself. Because even in the most rehearsed environment, the most carefully placed pose...something real happens.
I wait for the real thing. I know it's coming.
