Revenki's photos with the keyword: pinhole

Improvised, forgot it was today. The central image is from a hole "drilled" with an Xacto knife. The peripheral ones are from a tiny hole punch I had on hand. The dim one, the sharpest of the bunch, was a hole I drilled with a pocket knife on the spot. Smallest hole, sharpest image (in reality, not quite so here), but least light.
