Digital pinhole

I made my own pinhole camera years ago in uni with a can. I remember painting the inside black and putting some sort of aluminum-foil sliding device to let the light in. You had to load the paper in the darkroom, go out and take your photo, and come back inside to unload your exposed paper and develop it —or put it in a protected box for developing later.

Now with digital photography, I learned there are special caps that do the trick without the hassle. I’m not just yet getting one of those, but I made a couple experiments with a black cardboard over my camera body without a lens. The first pinhole was too big, and everything came excessively blurred. So I did another one with just the very tip of the pin.

The photos are not great, but it was fun to experiment just a little. I don’t want to ruin my camera with dust or something —you can actually see a very visible and focused particle in the bottom left corner of both photos. If later on I want to pursue more of this project, I’ll just get a manufactured cap for the purpose.

The top photos are with the pinhole cardboard, and the bottom ones are their equivalent with an 18-55mm lens. The equivalence is not so much in the sunset one, which was taken at 18mm, something the cardboard is obviously not capable of achieving.
