[dropcap]M[/dropcap]odular shutters enable instant conversions of boxes and containers into cool pinhole cameras. This shutter is an extraction of the extremely popular and reliable Flyer and Clipper II shutter mechanism. Mounting ears allow you to screw or glue the shutter onto just about any enclosure you can imagine. The pinhole is held in with an O-ring and can be easily popped out and swapped for a zone plate, mega pinhole, slit, another size pinhole, or neutral density filters can be added for suntrack (solargraph) exposures. A pack of modular shutters is perfect for classroom use as it shifts the focus from trying to get the pinhole and shutter right to thinking about the focal distance and imaging plane. Printed in black plastic, it is strong, robust, and light – perfect for professional, amateur, or educational use.

If you have access to a 3D printer, you can make your own cameras!

You can find or make your own parts (see Flyer Support section below).

Use 2-56 or M2 screws or bolts to fasten shutter to a light tight box or can, with black felt or sealant between the mount and the mounting surface.

The minimalist guide to operation:

  1. Load film or paper
  2. Open shutter
  3. Close shutter
  4. Advance or process film or paper
  5. Repeat

Exposure Table

Measuring Exposure Time

I recommend using one of the phone apps listed below. If you will be using a light meter, you will need to create your own exposure tables depending on your pinhole size and focal length.

There are many ways to do this, but one is to use the calculator at http://www.mrpinhole.com/exposure.php.

You will first need to calculate your f/stop by dividing your focal length by your pinhole diameter (in the same units – in or mm).
