Those amounts are, um, really high. True, not for a famous model working with a famous photographer on a big commercial shoot. If you're talking a more "average" photographer and a non-professional model, it'd be more likely be under $100 but that of course depends on how many rolls they're taking, how long the shoot is and under what conditions.
Personally I have no interest in being a model of any sort but I felt I'd just contribute that.
