Might have to make myself one.
    If a contact print at arm's length is too small to see, you need a bigger camera. :D

    My pinhole experiment is kinda boring.

    I failed to vary exposure far enough. Only 1 stop...But the lights did vary by type. All studio, no daylight at all.

    All shot on tripod with 5.5" bellows extension, 0.5 laser cut pinhole, 8x10 Ektascan ISI 50 in Fidelity holders. Remarkable how close the registration is on all 4 when stacked by hand on light table. No the scans don't register and are crap quickies. Mr Pinhole calculator. Google it.

    12' lens to white paper with 1-4 lines. Notice the Calumet Exposure Calculator above the paper. Straight scans at 300dpi No PS except to re-size for here.. Actual width seen on film is 14 feet.

    3 Einsteins full power at 6, 7, 8 feet semicircle. When using only modeling light it was 3-250 watt and one 100 watt LED and room light.

    On light table with loupe I can read the writing on the bottom drawers, my notes on exposure on the white paper and "Calumet' on the Exposure Calculator. But not in these scans.

    Randy,

    This was one of those tests that gives an answer to some apparently "stupid" questions. Great! Besides the light type, where they different in terms of wave length / temperature?

    Regards

    The strobes are 5600K and the tungsten model lights look pretty yellow to me, maybe 3400K.

    I wanted to check angle of view. The falloff at the corners is not only normal falloff but I really didn't illuminate the corners.

    I also wanted to see how sharp I could get the center at 5.5" bellows and 0.5mm pinhole. Pretty sharp. imho

    I want to build a one shot box camera to the same dimensions and use it for 'Detective camera' street shots.

    I will hide the box in plain sight. More on that later.
