35mm and any other camera with removable lens:
a) Remove lens
and tape pinhole over opening
b) You can add
cardboard or plastic pipe "extension" tubes if necessary.
Or you can drill a quarter inch hole in a plastic body cap and tape the pinhole over this. Has the advantage of being easily interchangable with "lenses".
There are also commercially available body caps with the pinhole already in place.
Oatmeal boxes and other
a) Only one piece of film/paper at a time.
b) Make sure
it is light tight. A good way to do this is to paint interior flat black.
Remember to make the plastic lid opaque too.
c) Use black
opaque tape to seal edges where box is opened
d) You can produce
the most "bizarre" images, because of the shape of the film plane.
e) The oatmeal box does not
look like a camera (candids, etc.)
Paint Cans - most hardware
stores have these for $1-2 for the qt. size..
A one quart can
will hold a piece of film or paper up to 4x10 inches. Use MATT or PEARL paper,
GLOSSY causes strange vertical reflections. A #80 drill will produce the sharpest
images on a one quart can. Paint the inside and bottom of the lid with flatblack
paint. Use a large washer or quarter to undo the lid afterwards. Make sure the pinhole itself is clean.
Easy to get paint, etc. into the pinhole.
Pinholgas - 120 film pinhole camera made from a Holga plastic camera (working on this page)
4x5 see also Foam
a) This is one
of the most universal film formats, lots of film types available, including
Polaroid (Fuji still make film pack films).
b) It can be
made from a variety of materials from foam core to wood to plastic to metal.
c) It allows
for more than one image to be taken by using removable
film backs and film holders.
d) You can adapt
a "real" 4x5 camera easily by removing lens and adding a pinhole
to a lens board. Of course, this can also be done with other sheet film cameras
from 2 1/4 x 3 1/4 to as large as you have!
None of the above is useful if you have not made your PINHOLE
