I figured most of my non-photographer/model followers wouldn't know what a TFP shoot is, so here is a quick explanation I put together (internationally applicable/relevant):
TfP stands for 'Time for Prints' (also known as TFCD - Time/Trade for CD).
This term describes an arrangement between the photographer and model, which concerns an unpaid photo shoot. Essentially, the agreement entails free usage of the photos for non-commercial purposes, such as the extension of the model's/photographer's portfolio. TFP shoots are sealed with a contract, which regulates the amount of photos the photographer is required to deliver to the model and the format thereof, as well as the time limit for delivery.
(The specifics vary, however, most contracts also require the model to confirm that the shoot did not involve coercion, and that the photographer is given complete freedom in terms of editing, so long as this editing does not intend to ridicule the model, or portray him/her in an undignified manner. Sometimes the contract requires the photographer and/or model to source the other whenever the photograph is used in a social network or any other type of media.)
My version of the contract requires me to deliver 10 photographs (JPEG) from the TFP Shoot within 21 days. It also prohibits the model from making any changes to the photographs themselves.
(Note: the TFP contract is easily trumped by general personal rights and rights of publicity in court, and serves as more of a formality - a fact that many models and photographers are not aware of.)
