My portrait business model is simple: One Fee covers the Photography Session, provision of Proofs, editing selected Proofs and delivering Edited, High-Resolution Files to my clients. Clients are free to have pictures printed wherever they wish, or can purchase prints from me---I use the best photography labs in the nation.
My Sports and Events business model is also simple: I request an Appearance Fee to attend the Sporting or Special Event and publish my pictures for purchase. Picture purchases are refunded against the Appearance Fee dollar for dollar until the Appearance Fee is fully refunded. If a client does not want me to publish and sell pictures taken during their event, I can deliver Edited, High-Resolution Files for a flat Appearance Fee. I can also arrange for prints, if desired.
