How would I cut a 1/64 inch hole for a pinhole camera? Answered

Has to be "1/64" no bigger or smaller reference "The Camera" by Ansel Adams. More than likely material that is going to need the hole is going to be a part of aluminum can.

1/64 drills are available, though you might find using a fine needle will be around 1/64" -try driving the needle into a piece of cork, then use that to hold it while you pierce the ali.

Although your happy with the answer - Allow me to offer a different and easier approach.

Drill a 1/4 inch hole in the can bottom. Cover with a patch of aluminium foil - for durability use the thicker foil or even a disposable foil baking tray for really thick foil.

You can easily pierce this with a needle for the aperture and it will produce a very round hole.

You can also replace it easily to try different sized needles to vary the aperture.

Have fun.

Are you talking about "f/64"?

If that's the case then the size of the hole is determined by the focal length of your lens.  In a pin hole the focal length is the distance from the pinhole to the film plane.
