Pinhole Camera: 2 Aesthetics

Main Project Plan: Pinhole camera

A pinhole camera is a very simple image making device that relies on the “camera obscura” effect. It is essentially a light-proof box with a very tiny hole in one side. This small hole, or aperture, lets a few light rays in that project an inverted image on the opposite wall of the box [1]. Often people put translucent paper on this wall so they can view the image, or put photo paper or film inside to permanently capture the image. I am an avid photographer, so this will be a fun exploration into analog image making methods.

The pinhole camera consists of a box, large enough to fit a 4″x6″ or 5″x7″ image on the back wall. These walls could be made of laser-cut wood or 3D printed panels that fit together. You can even construct one with paper, but I would want a sturdier box. The inside of the box will be painted black or lined with black paper so light doesn’t bounce around and change the image. The pinhole is poked through a thin material like recycled aluminum sheeting; the thin material is so there is less vignetting and the light can reach all edges of the photo paper. A shutter slides back and forth the cover the pinhole after the image is taken. This is usually done manually since exposure times for pinhole cameras are very long, but I am really excited by the possibility of designing a mechanism for the camera shutter.

This mechanism would be in two states: (1) shutter covering the pinhole (the default state) and (2) shutter removed from hole, with a timer that transitions state (2) back to state (1) after a certain amount of time from the user activating the mechanism. I’ve researched the mechanisms in mechanical clocks and mechanical timers to get some ideas but I still need to design and prototype the system sooner rather than later.

There should also be a method for putting the photo paper or film into the camera, like a removable back. I also want to put threads in the bottom of the camera so I can attach it to my tripod.

I imagined two different aesthetics for the project. The first was steampunk. According to the Aesthetics Wiki, “Steampunk engineering often includes visible gears and screws, as well as analog clocks, steam-powered machines (including vehicles such as airships that often carry flying wooden ships), rotating propellers and dials. Those are always made of metals, wood, or even glass, but never plastics or other modern materials. [2]”

I think an exposed shutter mechanism will lean into this aesthetics with the gears and springs that will likely be in it. I essentially have a box to decorate so I could also plaster old Victorian-type imagery and extra gears.

I also imagined the pinhole camera in a cyber/synthwave aesthetic. I could have grids or circuit traces decorating the sides and print a plastic shutter that manually slides open and closed for the exposure time.
