SV: Pinholing with SLR and extension tubes

Guillermo,

When I read your message it came to my mind that there are plastic caps used as covers, say for water pipes. Probably cheap and available in a good number of dimensions. Quite easy to sand before being pinholed also, which should be an advantage, since I believe that a thin pinhole cap makes more "sharp" pictures.

I have avoided 35 mm film just because of that it has to be enlarged a good number of times. However, there are some motives with a few elements of substantial size and interesting shapes and/or colors that could turn out right. I shall give it a try (when I find the time).
