Pinhole Photography
Characteristics of pinhole camera photography, Pinhole photographs have nearly infinite depth of field, everything appears in focus. As there's no lens distortion, wide angle images remain absolutely rectilinear. Exposure times are usually long, resulting in motion blur around moving objects and the absence of objects that moved too fast.
How are pinhole cameras made
The pinhole may be punched or drilled using a sewing needle or small diameter bit through a piece of tinfoil or thin aluminum or brass sheet. This piece is then taped to the inside of the light-tight box behind a hole cut through the box. A cylindrical oatmeal container may be made into a pinhole camera.
What kind of photography do they make?
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 they are 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 the flashlight. The smaller the pinhole (within limits), the smaller and sharper the point of light that the flashlight creates.
