    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:

    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.
