A woman has her clothes off and stands in front of the camera....
Some are seeking a new experience, having never done this before and wondering what it would be like.
Some see it as a challenge to themselves and to the world to stand naked before it.
Some are making a statement that they are adult, mature, free-spirited, and very very very confident in their body.
Some quietly withdraw, dealing with inner thoughts of "Oh God, I'm naked, what the heck am I doing?"
The Student Model thinks "It pays twice as well as any other job on campus and all I have to do is stand here naked."
The neophyte but practical model thinks "I really don't have the skills for a job but I don't mind taking my clothes off."
Some are kind of resigned, working out a favor for or repaying a debt to a photographer and wondering how much longer this will take.
Some models have circumstances that lead them to modeling as a last resort, "I can't hold a regular job but if I can make enough artists happy, there's the rent, grocery , and spending money."
Some let their vanities take control, thinking of the best way to present themselves and hoping the photographer has the skill to record what a damn fine looking body she's got.
Some see it as an inherently sexual experience, the camera as stand-in for all the folks she looks to seduce with her image.
Some see it as a very sexual experience, the camera a chance and an audience for her to indulge her erotic desires.
Some are lovers, letting the public see that which the photographer enjoys in private.
Some are indulgent spouses, putting up with their partners’ needs for bodies to photograph.
Some become very detached, thinking of themselves solely as a tool to work out the photographer's vision.
And some become a nymph, happily playing without thought or artifice.
