Pinhole Photography
the needle point has penetrated. (The edges of the pinhole should be sharp).
Then place the metal on the cardboard back side up and cautiously spin the
needle in the hole to make sure the hole is round. The hole can be checked
with a magnifier or an enlarger. You can also use an enlarger or slide
projector to check the diameter of the pinhole.

Can Cameras
Pinhole cameras can be made of many kinds of light-tight containers. A
cylindrical cardboard container, e.g. an oatmeal box or a herb tea container,
is easily converted into a pinhole camera for pieces of 120 roll film or
photographic paper.
1. Start by making a cardboard film holder. The film holder is made of
two pieces of cardboard which fit the internal dimensions of the
cylindrical box (Sketch). One piece (A) serves as the back of the film
holder. The other piece is cut in two, one small piece (B) which is
glued to A and a larger piece (C) with a cut-out window (D) for the
film or paper. Use some good tape (electrical tape or other) to attach
piece C to B. The film holder will be loaded in a darkroom by
placing a piece of 120 roll film or photographic paper between A and
C.
2. The film holder fits into a groove on either side of the box. The
groove is made by gluing cardboard strips to the insides of the box
(Sketch). You may make a supporting back (E) for the film holder by
gluing a piece of cardboard in the groove. This will make it easier to
slide the loaded filmholder into the groove.
3. Spray the insides of the box (including the lid), and the outsides of
the cardboard film holder, with flat black spray paint. Make sure the
lid is not translucent. If necessary glue some black plastic lining or
cardboard to the lid to make it opaque.
4. Make a hole in the front of the box. The "optical axis" should extend
to the center of the window in the film holder – provided you are not
looking for special off-center effects.
5. Then make the pinhole plate. See above.
6. Tape the pinhole plate to the front of the cylindrical box.
7. Make a simple shutter by taping a flap of black plastic over the
pinhole, e.g. plastic from a photographic paper package. The flap
