So...
I organized and taught a workshop. I had about 8 photographers, 2 models, and a makeup artist.
The event went pretty well. I don't assume anyone's skill level so I basically started from a level where everyone appeared to be comfortable with. And needless to say, there were some complete novices as well as a couple of seasoned veterans. But for the most part, they all had things to learn and I was more than happy to try to explain to them before the shooting actually began.
Unfortunately, 2 of the original 3 models were unable to attend, but the 2 that I did have were real troopers...
