Photography is the technique of capturing photos (capturing light) on a light sensitive recorder such as a film or a sensor. The word comes from French, “photographie”, which is related to the Greek word “phos” referring to the idea of “drawing with light”. Modern photography was encouraged by the developing of cameras; the camera is a device that uses an image sensor or a photographic film as a sensitive medium. The film itself can be the recording support but a digital card or magnetic memory can also be used.

Modern cameras have replaced the film with an image sensor (a light-sensitive electronic item), the resulted photo is stored on an electronic platform but it can be easily printed on paper or film. Many characteristics of the camera itself can influence the pic quality, the focal length, the type of lens, the filters and the scrims can all have a word in the quality of your pics. Most modern cameras are designed to automatically adjust advanced settings helping a newbie a lot. Moreover, advanced users can look through the camera menus and make custom settings that fit their purposes best. Photography has become more and more a hobby and an art in the same time.

Photography gained the attention of scientists from its very beginning, the possibility to record research steps or stages as part of experiments fascinated everyone. Military and police forces started to use photography for surveillance, data storage and recognition of criminal suspects. Nowadays, not even commercial advertising would exist without photos. All these are actually based on the idea that a photo contains very complex information details much larger than any description.
