What is a release? A photo release form provides consent from the model and/or photographer to use the photographshs for personal and/or commercial use. In general the photographer owns the rights to photos however a release clarifies grey areas of commercial sale, reproduction and/or work-for-hire statuses.
What is Time-For-Print? Time for Print (also called TFP or Time-for-Pics) is a common agreement between the photographer & model in which the actual photographshs are considered payment. Under this arrangement both parites share some ownership of the photos (how much ownership is generally specified in the release).
What is gratis? In the event that either the model or photographer will exclusively own the photos (generally because one has paid the other) they may elect to allow the other a select number of complimentary photos that can be used for porfolio purposes.
