What is a pinhole camera?



What is a pinhole camera?

A pinhole camera is a camera without a lense, but a very small apeture made using a pin, allowing light to enter the box from one side only. Once the hole is exposed light from a scene passes through it and reflects onto the opposite side of the box, creating an upside down image of your chosen scene. If the apeture is small, it will create a sharper image compared to a large appeture.

 Due to the fact that this camera needs a large amount of exposure, the shutter can be manually operated using a black piece of tape (any liht proof material) to uncover and place over the hole.

Joseph Nicephore Niepce was the first person to create a photo using photo obscura.
