Street photography, also known as candid photography, is one of the photography genres, where the daily street life is photographed. Street photography at its essence means candid photography of people and their activities. A street photograph must be realistic and lively, and an un-posed moment should be captured. We can also say that street photography is documenting human life. In this genre of photography, expressions, emotions, body languages of the subjects or persons are the important factors. Photojournalists, photo bloggers, documentary makers usually capture street photographs.

Candid photography is one of the types of photography, where a photograph is captured, without creating any pose or posture. This is not related to the knowledge of the person to be photographed, and permission is not taken as well. There is no need for planned posing, no choreography, no costumes. Just the pure spontaneous moment is captured. An image can be captured with someone in action. That makes the photo much more lively and realistic. Candid photography frequently utilizes sufficient natural light without using flash light. This is intentionally done to take pictures of persons or subjects, without letting them notice that.
