PHOTOGRAPHER FACT

The exclusive right of photographers to copy and use their products is protected by copyright. Countless industries purchase photographs for use in publications and on products. The photographs seen on magazine covers, in television advertising, on greeting cards or calendars, on websites, or on products and packages, have generally been purchased for this use, either directly from the photographer or through an agency that represents the photographer. A photographer uses a contract to sell the "license" or use of his or her photograph with exact controls regarding how often the photograph will be used, in what territory it will be used (for example U.S. or U.K. or other), and exactly for which products. This is usually referred to as usage fee and is used to distinguish from production fees (payment for the actual creation of a photograph or photographs). An additional contract and royalty would apply for each additional use of the photograph. For example, the photographer may sell the use of one photograph to different companies for use on calendars, cereal boxes, magazines, greeting cards, or many other products, in many countries.
