Today I am going to talk about pinhole cameras and go over how I changed my camera cover into one.
To start a pinhole camera is basically a tiny hole that takes the place of the lens and has been around for longer than photography. It used to be used as a drawing aid, and later was used with film and light sensitive paper. Now when I say a tiny hole I am not talking about f22 or f32 I am talking around f160-f200.
With the aperture being so small the images generally turn out blurry because of the high diffraction. Diffraction in photography is basically light waves interfering with or bouncing off of each other because they are all trying to get through a small opening. It is way more complicated than that but that idea should suffice for my purposes here.
The pinhole, I feel is more like an Impressionistic painting than a photograph. One other thing with the pinhole is that if there is any dust on the sensor it will be very visible.
The pinhole cap that I have is old and beat up so I am going to redo it taking snaps along the way to show how it is done.
On to the making of one. Supplies needed are 1) a camera body cap 2) a drill with a 1/4 inch or so bit 3) fine grade sandpaper 4) foil 5) small gauge needle 6) tape
Put it on you camera and try it out.
It’s fun and gives a different look and feel for photography. If you try it share your pictures I would like to see them.
