What is a Pinhole Camera?
A type of camera in which the 'lens' is
simply a very small aperture, or pinhole.
This camera uses the principles of
straight-traveling light paths and
reversibility of light paths to form
images on a screen or film

Get a light proof sealable container
Paint the inside flat black or use
black paper

Punch a hole in one end
This is to put the lens on, and is not
the aperture itself

Carefully poke a hole into a piece of
aluminum with a needle to create the
“lens”

Tape the lens to the body with the
two holes aligned
Create a cardboard shutter and tape
it to the body over the lens

You will not be able to hold your camera
still for such a long exposure. Make sure it
is wedged or leaning on something so it
stays still for the entire shot.
Lift the shutter and time the exposure
accurately. No counting “mississippis”
Bring your camera into the darkroom and
remove the paper and process it. Use the
same times as the photogram.
