I actually did a little photo shoot for a girl in a barter exchange a few years ago.
I actually record on my phone several movies of her over the period of 3 hours, involving multiple clothing changes, etc.
I never said anything would be usable, but she spent a few months picking individual shots out which is all part of her usable gallery and when she thinks she wants something different, she just uses the same technique now to get more.
no on needs to be very professional nowadays.
