World Pinhole Photography Day

World Pinhole Photography Day is a worldwide celebration of the pinhole camera. It is the simplest device that allows you to take pictures. It is the predecessor of modern cameras. The holiday is celebrated annually on the last Sunday in April.


The history of World Pinhole Photography Day is devoid of details. Many agree that the holiday started in the early 2000s.

To learn more about the camera obscura, it is necessary to go back a few centuries. The first written evidence of the operation of this device is described in the book “Stereoscopes” by D. Brewster, which dates back to 1856. The principle of operation is the transmission of light through holes whose diameters do not exceed the diameter of a point. This method was used even by the great medieval scientists. Leonardo da Vinci used the point hole in art. When using the telescope obscura, scientists were quickly blinded. Then they were upgraded to a camera obscura, which gave additional shading, and the sun did not hit people’s eyes.

Interesting facts

  • The underwater mollusk’s visual apparatus called the “nautilus” works on the principle of a camera obscura.

  • The first camera obscura was developed by Johann Tsang back in 1686. It was equipped with a mirror tilted at 45°.
