Early Photography

In the early days of photography, a stand or some other firm support for the camera was essential. This was because photographic materials were were so insensitive to light that a typical exposure lasted several seconds. The camera would have to be held still for this time in order to obtain a sharp picture. The subject also had to bestill if their images were to registed properly on the flim, Some early street scenes include blurred, transparnet, ghostlike images of people who wandered past while the scenes was in process of being photographed.

Studio portaits from the late 1800s show people posed rigidly, often learning against furniture, which helped them to remain motion motionless. As it was important to keep the head still, a support was often provided for the neck. Bright studio lights, sometimes produced by set to a strip of magnesium or a small pile of magnesium powder, helped by reducing the required exposure time. These burned with an intensely blue flame that gave the nescessary amount of light, but the smoke was unpleasant and there was also a risk of fire.

The problems associated with long exposure were overcome by the introdution of faster, more sensitive photographic plates, and later, roll films. The development of smaller cameras led to photography becoming a popular hobby. Nowadays, digital cameras have further revolutionised photography, enabling even the most inexperienced of photographers to produce professional - looking pictures.
