Today I stopped in to NYCResistor and I made a lensless lens for my digital camera. I had a lens cap left over from when I had my camera stolen and so I drilled a hole in the cap and then cut a piece of aluminum from a pop can that would cover the hole. I sanded the aluminum down with fine sandpaper so it was really thin. (Don’t breathe the dust!) Then I poked it with a pin and then sanded the hole down. I checked that it was round by holding it right up to my eye and looking towards a light. Then I taped it onto the backside of the cap and made a little cover using tape for the frontside of the cap. The cool thing about pinhole photography is everything is a little blurry, but it’s all blurry in the same way, there is no focusing!
