I find it hell alot easier when its a model who has done a few shoots before, this was her first one, and trying to directing her, it was difficult. When you have experienced models they are great to deal with, they bust out lots of poses and moods.
I was trying to balance the flash with ambient and get the critical focus, so juggling it all was a pain. Still i had fun, and learnt some more about flash lighting.
I sometimes wonder if bringing a book of poses would be a good idea, or would that not come across as professional.
