The original concept of camera dates from Grecian times, when Aristotle referred to the principle of the camera obscura (Latin=dark chamber).

The first diagram of a camera obscura appeared in a manuscript by Leonardo da Vinci in 1519.

In 16th century brightness and clarity of camera obscuras were improved by enlarging the hole and inserting lens.

In 1800 Thomas Wedgwood makes "sun pictures" by placing opaque objects on leather treated with silver nitrate; resulting images deteriorated rapidly, however, if displayed under light stronger than from candles.

In 1814 Joseph Nic�phore Ni�pce achieved first photographic image with a camera obscura - however, the image required eight hours of light exposure and later faded.



In 1837 Louis Jacques Mand� Daguerre uses his daguerreotype method (called after his name) - the first image that was fixed and did not fade and needed under thirty minutes of light exposure.

In 1841 William Henry Talbot patented the Calotype process - the first negative-positive process making possible the first multiple copies.

In 1851 Frederick Scott Archer invented the Collodion process - images required only two or three seconds of light exposure.

In 1859 the panoramic camera is patented - the Sutton.
