Description
A pinhole camera is a light-proof box with a small hole in one side that lacks a lens. The camera obscure effect occurs when light from a scene enters through the aperture and projects an inverted picture on the opposite side of the box. To make the image, only a small piece of the camera (about the size of a pin) must be exposed to the outside. As a result, this camera can be concealed in other items and remain undetected.The size of a pinhole camera is one of its key advantages. Due to the lack of a lens, these cameras can be made in a variety of sizes, including small and unobtrusive. As a result, pinhole cameras can be camouflaged as pens, headphones, or even eyeglass frames.
