I will readily admit that posing people is not something I'm used to doing. Sports shooters have it easy in this regard. It's just a Nikon D3s on each shoulder on a harness thing, 300mm on one, 70-200mm on the other, maybe a third body around the neck with a 24-70mm. Easy (sports shooters will kill me for this). People skills aren't really necessary. For portraits, however, you have to verbalize and build rapport with models. That is something I have some improvement to do.
Neil van Neikerk and Joe McNally seem to have a very easy attitude with their models. Their experience in wedding and general portraiture, respectively, allows them to know what they want quickly, and the ability to verbalize (or in Neil's case, act out) the pose. I think I need some inspiration. Neil suggested clothing catalogues and practicing the poses yourself in a mirror. I just might do that.
I've seen videos of Annie Leibovitz posing people, and she does not look as comfortable. It's strange, considering her end result. Perhaps it is because of her reputation that she does not need to relax her subject; they are already relaxed. I remember her saying that she still does not feel particularly comfortable building a rapport with her subject. It doesn't show in the pictures.
I guess I have more work to do. Hopefully you won't find me striking poses anytime soon. I can guarantee it won't be pretty.
