This is what it looks like on my Benbo tripod.
And here’s a closeup of what it used to look like š
I have already torn off the aluminum and plan to replace it with a small circular copper-colored shim, of which I seem to have quite a lot.
And in looking into pinhole sizes (my obsession of last week was misdirected), I discovered that pinholes are not always, well, pinhole sized. These cameras’ pinholes range from 2 to 4 mm. 2mm equates to 5/64 of an inch, a common drill size. So I could have saved some mental turmoil and just drilled a hole in something, rather than poking a hole and then trying to figure out what size it was.
Ah, snap. I misread the captions under those images and yes, they are pinhole-size or damn near. O I guess I will knock off the ubiquitous copper shim I had planned to use and think up something different.
Using PinholeCalc, I see that that size gives me a manageable exposure time of 1 second for most things I could be interested in doing.
Interestingly, PinholeCalc recommends a much smaller aperture than that: .245 mm or something smaller than 1/32″ somewhere between a 72 or 73 on this page. Not sure I can find that locally, but I’ll see. The values change quite a bit:
