Photography is an art and a science, it is highly practical or functional and purely aesthetic, it all depends to what use we put it. Many businesses (like home photography business) 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. Other than this one major application of photography, people take pictures because they like it and they can.

The history of photography begins with the invention of camera obscura in the antiquity but so many steps have been made ever since. 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 usage of photography for very long lists. Together with the recorded videos of a certain event, pictures provide highly reliable scientific evidence. There are military, archaeological, forensic, data storage and geographical applications for photography, and these are the largest and most extensively used. Personal documents always include photos, and this is the  main way of recognizing identity. Besides the wide-range usage, photography also plays an important part in entertainment, personal life and memories preservation.

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. The technology has reached such an extent that photography dominates so many intimate moments in our lives. There is no baptism or wedding 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 this photography that is, in a sense, less of a photography business, but this falls into the realm of art… and there is hardly anything commercial about it. So many art galleries now house photography exhibitions worldwide. They are invited to commemorate events, support shows or just give expression to a feeling, an opportunity, an occasion that would otherwise be lost for good. Artistic photos contradict everything that is practical or commercial: their purpose is to express and delight artistically.
