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.
What just about every scene kid and hipster under the age of 25 calls themselves these days. Many own Canon Rebel xtis and rely heavily on cropping and Photoshop filters to give their otherwise mundane photos an "artsy" feel. It is also not uncommon to see them wielding Lomography cameras (usually a Holga, now that they're sold at Urban Outfitters) on any given day. Typically, these "photographers" cite Diane Arbus, Robert Mapplethorpe, or, in the case of those Vice Magazine devotees, Terry Richardson, Cobrasnake, or Richard Kern, as major influences, because they couldn't name any other photographers to save their lives.
The typical subjects of their photographs include, but are not limited to: pidgeon-toed girls in Converse that have been drawn on with ballpoint pens and/or Sharpies, flowers/weeds growing out of cracks in sidewalks, juxtapositions of objects that typically don't go together (in one such case, a Queen of Hearts playing card on a cracked sidewalk), a girl who looks like something out of an American Apparel ad smoking a cigarette, decaying buildings, and just about anything that looks "vintage" (ie, yellowing washing machines in a laundromat).
16-year-old Dylan took to calling herself a photographer after receiving her Canon Rebel for Christmas, and snapping a few photos of sidewalks in Decatur.
"These photos represent the irony of life," she said.
"And you represent the bane of modern photography," David replied.
