As in other arts, the definitions of "amateur and "professional are not entirely categorical. A professional photographer is likely to take "photographs to make money, by salary or through the display, sale or use of those photographs. An "amateur photographer may take photographs for pleasure and to record an event, emotion, place, as a person without a monetary motivation.
A professional photographer may be an employee, for example of a newspaper, or may contract to cover a particular planned event such as a "wedding or graduation, or to illustrate an "advertisement. Others, including "paparazzi and "fine art photographers, are "freelancers, first making a picture and then offering it for sale or display. Some workers, such as "crime scene detectives, "estate agents, journalists and scientists, make photographs as part of other work. Photographers who produce moving rather than still pictures are often called "cinematographers, "videographers or "camera operators, depending on the commercial context.
An amateur may make considerable sums entering work in contests for prize money or through occasional inclusion of their work in magazines or the archive of a "photo agency. The term professional may also imply preparation, for example, by academic study, by the photographer in pursuit of photographic skills. There is no compulsory registration requirement for professional photographer status, so ambivalent or overlapping concepts apply here as they do in other areas of unregulated artistic activity, such as "painting or "writing.
Photographers are also categorized based on the subjects they photograph. Some photographers explore subjects typical of paintings such as "landscape, "still life, and "portraiture. Other photographers specialize in subjects unique to photography, including "street photography, "documentary photography, "fashion photography, "wedding photography, "war photography, "photojournalism, "aviation photography and commercial photography.

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.
The contract may be for only one year, or other duration. The photographer usually charges a royalty as well as a one-time fee, depending on the terms of the contract. The contract may be for non-exclusive use of the photograph (meaning the photographer can sell the same photograph for more than one use during the same year) or for exclusive use of the photograph (i.e. only that company may use the photograph during the term). The contract can also stipulate that the photographer is entitled to audit the company for determination of royalty payments. Royalties vary depending on the industry buying the photograph and the use, for example, royalties for a photograph used on a poster or in television advertising may be higher than for use on a limited run of "brochures. A royalty is also often based on the size at which the photo will be used in a magazine or book, and "cover photos usually command higher fees than photos used elsewhere in a book or magazine.
Photos taken by a photographer while working on assignment are often "work for hire belonging to the company or publication unless stipulated otherwise by contract. Professional "portrait and "wedding photographers often stipulate by contract that they retain the copyright of their photos, so that only they can sell further prints of the photographs to the consumer, rather than the customer reproducing the photos by other means. If the customer wishes to be able to reproduce the photos themselves, they may discuss an alternative contract with the photographer in advance before the pictures are taken, in which a larger up front fee may be paid in exchange for reprint rights passing to the customer.
There are major companies who have maintained catalogues of "stock photography and images for decades, such as "Getty Images and others. Since the turn of the 21st century many online stock photography catalogues have appeared that invite photographers to sell their photos online easily and quickly, but often for very little money, without a royalty, and without control over the use of the photo, the market it will be used in, the products it will be used on, time duration, etc.
Commercial photographers may also promote their work to advertising and editorial art buyers via printed and online marketing vehicles.
Many people upload their photographs to "social networking websites and other websites, in order to share them with a particular group or with the general public. Those interested in legal precision may explicitly release them to the "public domain or under a "free content license. Some sites, including "Wikimedia Commons, are punctilious about licenses and only accept pictures with clear information about permitted use.
