my old pinhole camera

[compur]

I just came across this 4x5 pinhole camera I made some years ago out of
mounting board, balsa wood and gaffer tape mostly. The pinhole was made
from a piece taken off the black plastic inner envelope from a box of
printing paper. The hole was made with a needle heated over a flame.

The design was strictly make-it-up-as-I-go. I would do it differently next
time but it seems to work OK.

Here is a shot from the camera (FP4 in Rodinal). Direct neg scan.

I think it gives a pretty sharp image for a pinhole.

Ha! That is a fantastic pinhole. Can't believe the detail you got with it.

You did a great job with this! :thumbup:

It's nice work !!! Excellent post and very comprehensive and useful list of tips. Thanks for providing such good information.

Novel approach to making the hole. Sounds easier than my endless sanding down aluminium pie plate. What aperture and focal length did you get?

It's about a 5" focal length. I have no idea what the diameter of the pinhole
is -- whatever the thickness of a standard size sewing needle is.

In full sun with ISO 100 film an exposure of about 10 seconds seems to work.
