A photographer is a person who takes photographs using a camera. A
professional photographer uses
photography to make a living, while amateur photographers take photographs for pleasure and to record an event, place or person.
Not all photographers are scene or emo kids and not all rely heavily on photoshop or any other photo editing software (such as GIMP, Lightroom, photobucket, etc) to make their photos look unique.
Some photographers actually are photographers, not just "What just about every scene kid and hipster under the age of 25 calls themselves these days.". Some actually shoot photographs for a purpose rather than because it is the "cool" thing to do at the moment. Some great photographers are Ansel Adams, Diane Arbus, Les Forrester, Lara Jade, Andrew Gransden, Joe Rosenthal, Jill Greenberg, and Annie Leibovitz.
A photographer may stick to one subject area, such as portraiture or nature strictly, but quite a few usually spread their subject areas among many different kinds of
photography, such as nature, portraiture, still life, photojournalism, urban & rural, and
architecture, just to name a few.
