Photography is a mechanical process that makes possible the recording of an image thanks to the light capture. It is also considered as an art (the 6th) for -even if a camera comes under technical research at first- it enables an sizeable artistic research. After having found an interesting frame to realize a shot and -why not- one or more protagonists, we can finally express our ideas, emotions and an atmosphere through photography.

Photography is also a means to keep in memory some historical elements or people at a given time. That is why we have today some accurate representations since 1839 (invention of photography) thanks to those who took time to develop this process.

From the beginning, photography had a great popular success. At the time, the richest ones would pay for artists' services to get their portraits done, but photography would allow everyone to take their portrait or pictures of their life. Realism that has always been sought in the paintings was doubled-cross by photography. Far from replacing painting, photography -on the contrary- freed it from its duty to be realist and let it free to become more abstract. Thus, artists got rid of the constraint to represent reality.

Nowadays, programs enable us to manipulate pictures. We can modify the light, the colors, correct defaults and change a part or all the picture. Its authenticity has become more relative, since reality can be handled. However, we could also remark that a photograph is already a form of manipulation of reality for it is the expression of a certain look. Frame, mainly, shows how subjective is photography.
