What is the nature of an image formed by a pinhole camera?

Depending on the precision with which your pinhole was made and its distance from the back of the camera, you will see surprisingly good detail, very straight parallel lines, little distortion and sometimes interesting edge blurring. Of course the image will be upside down and reversed. read more

Camera Obscura (dark room) is the Latin word for pinhole camera and from where we get the word camera. The first pinhole cameras were dark rooms with small hole in one wall and a facing wall where the pinhole image was projected. read more

Then, once inside the pinhole, the rays diverge. The vertical and horizontal inversions of the image when compared to the object can thus be explained by simple geometric logic. The analysis of the image produced by a pinhole camera demonstrates the rectilinear propagation of light. read more

A pinhole camera, also known as camera obscura, or"dark chamber", is a simple optical imaging device in the shape of a closed box or chamber. In one of its sides is a small hole which, via the rectilinear propagation of light, creates an image of the outside space on the opposite side of the box. read more
