Vintage imagery has an intriguing beauty, an escape from modern, super-realistic photos to a time when things were softer. There are many ways to add a filter to your snapshots to make them look unique, but why not do it naturally? Here's a simple way to turn a camera body cap into an authentic pinhole lens!
Things You'll Need
- A camera body cap
- A tea candle
- Hot glue gun or contact cement
- Sandpaper (200-400 grit)
Remove the Bottom of the Tea Candle
You'll need a piece of aluminum or brass that's just a bit thicker than kitchen aluminum foil. great place to find it is the bottom of a tea candle. Remove the wax cylinder and wick. Use scissors to cut out the aluminum.
Flatten the Aluminum
Rub your fingernail on the aluminum disc to flatten it.
Drill a Hole in the Aluminum
Place the disc on a piece of cardboard or wood and gently press the needle into the center of it, using a spinning motion. Flip the disc and gently sand the bump from the other side. Repeat the drilling from the sanded side, then flip sand the bump from the first side. Repeat as necessary. The goal is to make a smooth circular hole as small as possible. Use a magnifying glass to check your work.
The smaller the pinhole, the sharper your images will be. The trade-off is that the exposure times will be longer.
Drill a Hole in the Body Cap
Use a 1/4 inch - 1/2 inch drill bit to make a hole in the center of the body cap.
Drilling hole in plastic is a bit different from drilling holes in wood. You can buy a special bit for plastics, but a a normal wood bit will do, just take it slowly .
Glue the Lens into the Body Cap
Using either hot glue or contact cement, place the lens into the center of the inside of the body cap. Make sure that it's centered.
If using contact cement, put the cement on the body cap and don't let it dry before putting the lens in place. This way you can shift it around a bit to make sure it's centered, then let it dry. Contact cement is amazing stuff but if you follow the traditional "apply to both surfaces and let dry before attaching" instructions, you'll only get one chance at alignment!
Place the body cap on your digital camera and have a look! The extremely small aperture of the pinhole lens means you'll need to use a long exposure speed, very high ISO, or both. A tripod will help with the long exposure times and the graininess of high ISO fits with the vintage imagery.
