John,
If the pinhole is too small diffraction will overtake the circle of
confusion. Diffraction will add to sun flare. The lines in the frames
seem to extend to the border. Has the film gone through an Xray scanner?
I should have recognized my own town on the pictures but had to look
twice.

I just looked at your contact sheet. I bet you are
getting a lot of light into the meter from the
viewfinder side. Several exposures are severerly
underexposed.> --- john yeo

John:
Please describe your technique with making and
verifying a .006" pinhole. I have found it difficult
to make pinholes smaller than about .015". David

John,
I had some thoughts about your "vertical lines". They look to me like
artifacts of a sticking focal plane shutter.

I don't know what the vertical line is on some of the frames (17,18,28,29)
Maybe some of you can provide an answer to that.
sorry. fixed it now.

A few days ago I made a pinhole body cap for my canon AE-1. I made the pinhole
as small as I could, it ended up .0065 +/- .0005" f/270. Would using one of
the formulas to determine the optimal size work better for such a small focal
length? Or does that only apply to longer focal lengths. L
