Good suggestions, I'm sure most people feel the same way.  The html point
has been brought up many many times, but few people ever seem to change it.

While this may seem like the easiest method, you probably won't be very
satisfied with it (imho).  Making optimal pinholes for such a short focal
length is difficult, and the 35mm format is just too small for pinhole.
Yes, some have great success with it, but the results will be much better on
120 or larger film.

When the hole is too big, the image is fuzzy because each point of light
ends up with a larger spot on the film than it should.  When the hole is too
small, defraction occurs.  When you look at the edge of a shadow, it is
fuzzy.  That is defraction.  The edges of a shadow *should* be sharp, when
you think about it, but in reality they're not.  When the pinhole is too
small, the image becomes less sharp because of defraction.
