$\huge\underline\mathfrak\green{What\:is\:a\: pinhole\:camera}?$

A pinhole camera is a simple camera without a lens but with a tiny aperture, a pinhole camera – effectively a light-proof box with a small hole in one side.

Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.

$\huge\underline\mathfrak\green{How\:is\:it\:made}?$

In its simplest form, the photographic pinhole camera can consist of a light-tight box with a pinhole in one end, and a piece of film or photographic paper wedged or taped into the other end.

This piece is then taped to the inside of the light-tight box behind a hole cut through the box.

$\huge\underline\mathfrak\green{Explain\:the\:working\:of\:it}?$

A pinhole camera works on a simple principle. Imagine you are inside a large, dark, room-sized box containing a pinhole.

Imagine that outside the room is a friend with a flashlight, and he is shining the flashlight at different angles through the pinhole.

When you look at the wall opposite the pinhole, what you will see is a small dot created by the flashlight's beam shining through the pinhole.

The small dot will move as your friend moves his flashlight.

The smaller the pinhole (within limits), the smaller and sharper the point of light that the flashlight creates.
