Types of photographic modelling
all models should be careful to decide what they wish to do,
and stick to the descision
rates per hour will depend a number of factors
but mostly on the 'type' of modelling done
type is also referred to as the models 'level'

fashion catwalk for fashion designers - usually 5' 10" and skinny !
fashion editorial for magazines - model can be any size
fashion catalogue for clothes retailers - model can be any size
character eg: look alikes
specialist eyes / teeth / hands / legs / feet etc for advertising products or services
swimwear shouldn't be see-through
lingerie underwear - may include transparent undies
glamour maybe partial nudity - usually intended to titillate
topless just what it says - breast(s) will be on full view
implied nude final picture quite tasteful but the model will be nude when working, although no personal bits show in the final image
classic may be draped, but naked all the same
art usually low key image depicting a lot of shadow
figure definitely naked, usually tasteful

All models should appreciate that video is usually better paid but far more demanding than still photography

Photographers should respect models 'type' and not expect any more
