Functional, practical or purely aesthetic, photography lies somewhere between science and art. Many businesses depend on photography and the entire written media is supported by photo materials of events. People’s access to information would be incomplete without photography and everything that it brings. There is also great pleasure in photography and we tend to delight in the technological availability of means to take pictures with.

The beginning of photography can be traced back to the discovery of the camera obscura in the antiquity. For a long period of time, photography depended on films for the image forming device. In comparison with digital technologies, the film, as recording medium is considered obsolete. When exposed to light, the recording environment creates a latent image that is afterwards converted into a usable image.

We can hardly mention all the uses of photography for such long lists. Together with the recorded videos of a certain event, pictures provide highly reliable scientific evidence. Photography has military, forensic, archaeological, geographical, recognition and data storage applications. Identity control and personal documents require photos. Other than such official applications, there is the entertainment part of photography that we cannot ignore here.

All mobile phones have incorporated photo cameras, and the pictures we take can be immediately uploaded on the Internet with the possibility to access the world wide web from the cell phone. And we want to use photography to capture special moments and turn them into memories. There is no wedding or baptism without video recording and photo shooting. Or, consider for instance traveling, we will inevitably take at least one camera with us on our journey.

There is one other side of photography that is less commercial, but this falls into the realm of art. So many art galleries now house photography exhibitions worldwide. The camera thus captures emotions, gives a unique touch to reunions, celebrations and ceremonies, making things look much brighter when seen in retrospect. Artistic photos oppose everything that is commercial or practical: their purpose is to express and delight artistically.
