We have a general article on
explaining how they work and another project
a pinhole for your
plus two further projects using pinhole camera
So this article is a quick simple project,
that should take you no more than 5 minutes, that just demonstrates how a
pinhole camera works.
All we need is a Pringles tube, and yes you
can eat the Pringles first, and a piece of translucent paper
out of a cereal packet, or tracing paper. Something to cut the tube,
and something to put a small hole in the base.
Cut the tube off about 2 inches or so
from the base, you don't have to measure it. I used a bread knife and
sawed through it quickly.
Dust it out, to make sure there are no
bits of card or Pringles left.
Cut a piece of
the cereal box inside packet
or tracing paper to just a bit larger than the Pringle lid.
Make a small hole in
the centre of the base
of the tube. In the first version I made, I just stabbed it with a knife and
although this worked it was a slit rather than a round hole, in a second
tube I used a bradawl and hit it with a hammer.
Put the tracing paper or cereal packet
over the open end of the smaller part of the tube and put the transparent
Pringle lid over it to hold it in place.
the remaining part of the Pringle tube to form a viewing shield.
Tape it together if you want or just
Stand in the middle of a room and look
through it at a window, with your other eye closed, the tube being large
makes a good light seal around your eye even if you are wearing glasses.
Stay with it a minute or so for your
eye to become accustomed to the light level.
Ignoring the bright
light from the pinhole and looking at the image on the tracing paper, move
the tube about and you will find the pin point can be made to vanish and
the image moves about.
Notice that the image is upside down and
back to front.
