Well, I am not into digital imaging, so I tried a film pinhole camera on the
tongue of my shoe once, but the ladies wouldn't stay put
That's a "pinhole" video camera lens, which is actually a very small
glass lens. The video industry calls them "pinhole" lenses because they
can be mounted behind a very small hole for use as hidden security cameras.

Good answer. I have a super wide angle camera and the light falloff is quite
noticeable - note the infrared pinhole images at the bottom of

are with burning the middle 2-4 stops.
