I love pinhole photography. Did my photography class in college under an
instructor that experimented with all kinds of pinhole cameras.
When I was on the qt system we built pinholes out of chipboard with multiple
lenses/focal lenghts. The whole qt was devoted to the pinhole camera.
Students advanced to 35mm after that but they knew the workings of a camera
from the inside out thanks to the pinhole. Now I have to add on digital
Pinhole photography teaches the theories of light and camera functions better
than any other process. If it is something you can do...do it. I also like
to get a big refrigerator box, paint it black inside, put in a pinhole lens
and then sit the students inside the box so that they can actually see the
theories of light in action. They become the focal plane (with the help of a
piece of white drawing paper).
