Photography

Photography is known as the art of replicating pictures of people, objects or places in their exact likeness. These images can be transferred onto any photosensitive material and includes printing pictures as well.

The Source of photography is unquestionably the camera - the instrument or device that works on the principle of optics. Since the time the first camera was made, photography techniques have undergone extraordinary changes. The first models did not contain the film, but instead, consisted of 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'. The beginning of photogram came about when scientists discovered the quality of silver nitrate that changes its color when exposed to light. This would become a method to store images more permanently.

After this incredible founding they would place objects on the paper dipped in silver nitrate and expose it to the sunlight. After a while the area covered under the object stayed white while the rest of the space turned black. The outcome of this meant that the image formed was temporary - needless to say this method did not last long.

As time went by, the principles, methods and the material used in photography went through several changes. After some experimenting with various methods like Daguerre and calotype, they decided on collodion (also named the wet plate technique).

Modern day photography has made it possible to capture and preserve special moments, like birthday parties and weddings, to name but a few. History became more authentic with pictures, and photographs served as evidence in many cases. With the unbelievable technological advances in the art of photography, it is no more just fun and frolic but has taken on the dimensions of a full-time profession.
