Camera Obscura derives from Latin, meaning ‘Dark Room’.

This concept uses a projection of one image through a small hole, which means the image is inverted and also reversed, resulting in the image being up-side-down and displayed right to left.

How is the image inverted and reversed? Here’s how…

Natural and Artificial light both travel in straight lines, so whether the Sun is the source or the lamp sitting on the bedside table, the light waves are travelling straight. Light waves can be absorbed by an object or the object can make the light refract or reflect in direct directions. When using a ‘Camera Obscura Box’ the small hole will only allow certain light waves through, but only from a source that is directly in front of the hole. It works exactly like a retina; only a brain is able to turn what is being seen the correct way up.

The technology behind Camera Obscura is simply a box. Light waves travel from the source directly through the hole in the box (the source needs to be directly inline) and displaying a light image of the subject inside. If a mirror is placed inside of the Box at an angle, the image source can be displayed the correct way up.
