I have relatively recently started doing portraits, and am trying to get my head around posing models. Most photographers I've seen seem to take the approach where the model strikes a pose, they take a picture, and on to the next pose. Sometimes there's some tweaking going on, or even guidance, but the final photograph is largely a product of going with what works, serendipity, and luck.
But other visual arts (painting, sculpture, etc.) have a very different approach: you have only one shot at it, so the artist and model pose very deliberately.
There are surely pros and cons to the different approaches, as well as limitations due to the nature of the mediums. I was wondering how do other photographers pose their models? Does anyone get even close to the painterly posing method?
