What do TFP and TFCD mean?
TFP - Time for Prints or Time for Photographs
TFCD - Time for CD of digital images
A model, or would-be model agrees to give up her time and pose for a photographer who agrees to provide her/him with a selection of images for her/his portfolio.
For a model just starting out it can be a good way to pick up modelling experience and some images to start her/his book. For the photographer it gives him/her experience of trying different things and working with various models.
I hope that's explained it.
