I have noticed that models used to people who photograph with digital are kind of all over the place as far as moving around, more poses, more rapidly. It was a little surprising to me after having worked with slightly more art/life-drawing based models. But I'm a slow kind of person anyway so prefer the pace of my slow, plodding photography to the digital I was shooting that one time.
Don't be surprised by the ladies, Scott. We do actually take photography courses. We just don't like APUG for some reason (gee, can't imagine why considering some of the behaviour of the members here towards women...). All of my previous photography courses have been at least 50/50 male and female. If you're a serious artist, you're advised to do life drawing, on your own time if required like in my case. I was told it was expected to have some experience of it for my portfolio to apply to colleges and universities and my high school did not offer this (probably too prude to) but there was a local evening class group offering it. This and some more life drawing in college were my only background previous to any nude photography, and I was never in control of those models.
I wasn't much of a prude so I never asked if there was an alternative to life drawing for a portfolio but I gather it's seen as high brow and serious if you do work in it, at least occasionally, to prove you can draw people.
I guess fine art nude photography is another step up from that and possibly less required by photographic degree disciplines.
Oh to be able to have cameras and strobes, that'd be ace! Silly ancient cameras I have... Actually I guess one *can* be used with strobes but I don't have any and I still need to figure out how to tone down my pair of 500w halogen site lights to something less boiling, less eyebleeding hotlight...
And now I'm rambling

Though you're slightly inspiring me to make an effort again.
