location I can never remember & try 1 pic each....
I think you'll find it very interesting having a "zoom" pinhole camera..

  Subject: [pinhole-discussion] Pinholing with SLR and extension tubes

  This week I got an old SLR back from service, and I have a set of
extension tubes for it. An idea came to my mind, namely to use one or more
of the extension tubes with a pinholed lens cap or aluminum foil at front. I
could even get a second extension tube set and use these ones separately as
front tubes with permanent holes of different diameters that would fit
different combinations of the other tube set.

  Probably someone has tried this already, and if so I would be very
interested in learning the outcome of it as well as in getting some
suggestions for improving my idea.

  The best way is to try it out myself, but hey, I am the guy presently
converting a (too small) guest toilet into a darkroom, and that keeps me
busy enough for the moment.
