On Friday 28th March we were shown how to create a Pin Hole camera from an old drinks can. Having seen the work of Justin Quinell I was eager to make my own camera and see what I could capture.
To start with you will need
- Black Card
- Strong Electrical Tape (preferably black)
- A can opener
- A Pin (to make the whole)
- Light sensitive paper
- And a tin can (of course)
Cut a piece of card around 10 inches in length, it will need to be able to wrap around the outside of the can with a small overlap.
Make a series of cuts along the edge of the black card about half an inch in length. Do this all along the card.
Wrap the card around the can ensuring it is tight and secure with tape.
Place the can onto another piece of black card and use it to draw a circle, then cut out that circle.
Place the circle into the card tube you made earlier and fold over the flaps along the edge, this creates a lid for your camera. Secure the lid in place using tape.
You should now have something that resembles the above image (step 6). Check your lid carefully to see if any light is able to get through. If required add more tape to stop any light leakage.
Using the can opener carefully cut the top of the can away. If you are left with sharp edges then these can be filed down using sandpaper. This is also a good chance to ensure you can is clean and dry on the inside.
Using the pin, carefully make a hole about half way down the can.
Cover the hole with some more tape. Fold over the end of the tape so it is easier to use. This tape acts as the cameras shutter and will be used to allow light inside.
In a room under a safe light, such as a dark room carefully place some light-sensitive paper (7×5) is a good size into the can. The paper will wrap around the edges so you must ensure that it does not cover the pin hole. I placed a small piece of tape above my hole so I could see it easily. Then place your lid on top.
Your camera is now complete and ready to use.
It is extremely difficult to accurately calculate an exposure time. The hole acts as your cameras aperture and the first thing required would be to calculate what its f/stop is. This is achieved by dividing the distance from the hole to the paper inside and dividing it by the holes diameter. As I used an unknown pin size so was unable to ascertain my diameter so I decided to use the trial and error method.
My next post (here) shows how I got on.
