I have a
TFP contract that spells out what the model can expect, plus what they can or cant do with the photos.
The number they get depends on the shoot, but the exact wording of that part of the contract is
"A cd of full resolution images in jpg format, resized images for web use, and retouched images. Images to be a selection of representative images of those taken on this date."
It usually works out between 10 and 20 images, depending on the number of looks etc.
