    pinhole camera
  • A camera with a pinhole aperture and no lens

  • The most basic form of a camera in which no lens is used. A pinhole camera is made by making a lightight container and poking a pinhole in the front of the camera where a lens would go.

  • A camera whose lens is covered except for a pin-sized hole. You have a very small aperture, so you have to shoot long exposures.

  • A pinhole camera is a simple camera without a lens and with a single small aperture -- effectively a light-proof box with a small hole in one side. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box.











Pinhole Camera Negative and Positive




Pinhole Camera Negative and Positive





Cleaning out my basement and came across a box from a workshop I did about 25 years ago. The workshop was making and using a Pinhole Camera. The Pinhole Camera was a empty coffee can that was painted black inside. The paper (5"x7") that would become the negative was loaded into the camera in a darkroom.

Here is one example of a negative and positive from that workshop.

The negative was formed on a sheet of photography paper. After it was developed (darkroom skills) the positive was created by contact with the negative.

Oops! My pinhole camera takes ordinary 35mm film (which is handy) and has a very rudimentary winding on mechanism. Quite how rudimentary you can see from this unwitting double exposure. All the same I quite like the effect.

The foreground is cows grazing on Brean Down in Somerset; the background is the Gilbert White House museum at Selborne in Hampshire.
