Research & Development

The process of pinhole cameras have helped developed many technologies around today due to the principles of physics they brought about, which gave the initial idea to build on. The earliest discovered principles of pinhole photography came around in 5th Century B.C by a philosopher known as Mo Ti who became aware that objects reflect light in all directions, despite this discovery, no known photographic evidence of the use of a pinhole is recorded. In the Western Hemisphere in 4th Century B.C the writer Aristotle mentioned in his work; "Why is it that an eclipse of the sun, if one looks at it through a sieve or through leaves, such as a plane-tree or other broadleaved tree, or if one joins the fingers of one hand over the fingers of the other, the rays are crescent-shaped where they reach the earth? Is it for the same reason as that when light shines through a rectangular peep-hole, it appears circular in the form of a cone?
This observation remained unexplained until the 16th Century.

Pinhole cameras provided the means to enhance the idea and the principles of light travelling in straight lines and projecting images through small arpetures even convinced Pope Gregory XIII to correct the Julian calendar by ten days, through the use of a bronze ring placed high by a window in his cathedral, which created what was known as a "noon mark" which helped to tell the time of the day in 1580.

Modern cameras today gained the ideas from pinhole cameras, despite many new improvements, the science behind them are still extremely similar. The word camera derives from the latin term; 'Dark chamber' because of the way in which light has to travel through a small arpeture into a dark chamber in order to produce an image.
