Oh well….
A photographer, from the Greek φωτός, “light” and γράφω, “I write”, is a person who takes photographs using a camera. A professional photographer uses photography to earn money whilst amateur photographers take photographs for pleasure and to record an event, emotion, place or person.

If we accept that the above is statement is correct then that makes everyone who owns a camera (DSLR or not) a photographer. The only difference is whether you are a professional or an amateur photographer.
