The exact reproduction of all forms of pictures from one medium to another, is commonly known as photography. These images can be transferred on any photosensitive material. Photography includes taking and printing pictures.
The backbone of photography equipment is the camera, the instrument or device that works on the principle of optics. It’s hard to imagine what the earliest cameras were like, when you consider how sophisticated modern camers are. The earlier model did not contain the film; instead, it had a small light-shield box with lens and translucent screen on either side.
The image that traveled through the lens was stored on the screen. Known as ‘camera obscura,’ it was no more than a sketching device for artists. A major factor in the development of photography was the discovery that silver nitrate underwent a color change with exposure to light. This was the beginning of photogram, a method of making permanent images.
Another of the photography techniques they used was to place objects on paper dipped in silver nitrate and expose it to the sunlight. After sometime the area covered under the object stayed white while the rest of the space turned black. However, the image formed was temporary, so the method did not last long.
Over the centuries, the principles, the method and the material used in photography went through many changes. After experimenting with various methods like Daguerre and calotype process, finally collodion, or the wet plate technique was universally accepted.
Modern photography has given a totally new meaning to the entire perception of life and privacy. Photography has made it possible to capture and preserve special moments, in private and in public life. The advent of photographic evidence brought to life in great detail many historical events. People made their family tree in their albums.
Suddenly life was so much more fun and meaningful. With the tremendous technological advances in the art of photography, it is no more just fun and frolic but has acquired the dimensions of a full-fledged profession. Photography has many branches and types:
Aerial photography is the art of taking photographs from the air. Art photography is devoted to beautiful pictures for the sake of beauty only. Studio or advertising photography is dedicated to promotion of products and institutions.
Photojournalism takes pictures of events to support the news story and to create awareness among the people. Outdoor and travel photography is focused on taking pictures of landscapes and natural places.
Sports photography records images of the sporting events and games that take place in the world. Some types of photography like macro, scientific or close up photography are restricted to specific fields and are not widely known.
The charm of amateur photography lies as much in the end product as in the process of taking pictures. Perhaps the joy of browsing through family albums is one of the most precious benefits of recording family memories photographically.
