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. In fact, people have got used to seeing pictures for the columns they read. Other than this one major application of photography, people take pictures because they like it and they can.
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. A latent image is created on the film, and then it becomes usable when processed chemically in the studio.
We can hardly mention all the uses of photography for such long lists. Pictures are used for scientific evidence, in fact, together with recorded videos, they become the main proof in support or contradiction of a certain event. There are military, archaeological, forensic, data storage and geographical applications for photography, and these are the largest and most extensively used. Identity control and personal documents require photos. Besides the wide-range usage, photography also plays an important part in entertainment, personal life and memories preservation.
The average mobile phone user takes photos with the cellular. The technology has reached such an extent that photography dominates so many intimate moments in our lives. There is no baptism or wedding without photo shooting and video recording. Or, consider for instance traveling, we will inevitably take at least one camera with us on our journey.
As for the artistic dimension of photography, there is hardly anything commercial about it. 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 contradict everything that is commercial or practical: they have not direct functionality other than to delight and send a message to the viewer’s heart.
