Did you ever wonder how cameras work? With the marvel of digital equipment, it seems almost like magic. You push a button and the image appears instantly.

The first written record about viewing an image like that dates back roughly 2,400 years in China.

In the 13th century Leonardo da Vinci gave a detailed description, and using a pinhole camera, in the mid-1820’s Joseph Niepce, a French inventor, captured the first known photograph on bitumen-coated metal plate.
You might be surprised that the principal of the camera remains the same today. With the advancement of technology, pinholes were replaced by lenses made of very high quality glass, to project a tack-sharp image. The recording of that image also went through several changes and now a computer captures the image with the aid of sensors, that replaced the light sensitive materials.
