It helps us preserve important moments of our life as it can also capture beauty and emotion. Many people even pursue it as a hobby using it as a means to express themselves.

HISTORY OF PHOTOGRAPHY
Photography became possible when two distinct scientific processes were combined. The first of these processes is the optical process. The Camera Obscura (dark room) which is one of the primitive forms of camera had been in existence for at least four hundred years. There is a drawing, dated 1519, of a Camera Obscura by Leonardo da Vinci. About this same period, the Camera Obscura’s use as an aid to drawing was advocated. The second process is the chemical process. Many years before photography was invented, people had been aware of some concepts – for example, that some colors are bleached in the sun. However, they had made little distinction between heat, air and light. Gradually, concepts were realized and discoveries were made. Photography is the result of combining several technical discoveries.

Some important milestones:
• Albertus Magnus (1193/1206-1280) discovered silver nitrate.
• Georges Fabricius (1516–1571) discovered silver chloride.
• Daniel Barbaro described a diaphragm in 1568.
• Wilhelm Homberg described how light darkened some chemicals (photochemical effect) in 1694.
• The novel Giphantie (by the French Tiphaigne de la Roche, 1729–1774) described what can be interpreted as photography.
