You can of course use any 35 mm film, even colour. I discovered from the makers of Dirkon that, even when it was published, people often came up with improvements on their model. The design was significantly improved by sticking on a thin piece of metal with a hole, rather than making the hole in the paper, as described in the instructions. I didn't follow this suggestion, however, since I wanted to experience the real magic of Dirkon photography.

Finally, I decided simplicity was best. You load the film into the film back in a dark closet. Then you put the plastic film back into the camera.
To stop the exposure, you replace the dark slide. Then you take the film to the lab. Notice the clouds moving in the background. When building a pinhole camera, one of the most important things is the distance between the pinhole and the film.
This camera uses a pinhole that is. The focal length is and I hate to do this to you millimeters. Examine your progress with a magnifying glass. Build the Box Simple stuff here. The top and bottom are glued into rabbets in the sides. The front is attached using cleats. The back is hinged and also rests in rabbets in the sides. Begin by cutting your pieces to size.
Tape foil over the hole Tape a piece of aluminum foil over the hole. Poke a hole in the foil Use your pin or paper clip to poke a small hole in the aluminum foil. Try it out Place your second piece of card stock on the ground and hold the piece with aluminum foil above it foil facing up. Get creative For extra fun, try poking multiple holes in your foil, making shapes, patterns and other designs. Each hole you create will turn into its own projection of the eclipse, making for some neat effects.
Grab a helper to take photos of your designs for a stellar art project you can enjoy even after the eclipse has ended. Line up three plastic bins or trays in the light-tight room you used to load your camera. Developer goes in the first tray, water in the second tray usually stop bath goes here , and fixer in the third tray.
With the room dark and a safe light on, open the camera, remove the paper from the holder and process by placing the paper in the developer. Move the print in the developer for minutes. You should see an image form on the paper. If no image appears, you need to increase exposure time. Go back to square one, reload your camera and keep the shutter open longer.
Keep the light off. Rinse the negative in the water tray and transfer to the third tray with fixer. You can turn the normal room lights on after 1 to 2 minutes. Fix for around 5 minutes and rinse the paper for 15 minutes in running water. The result of a properly exposed pinhole photograph using photo paper will be a negative image.
Here is an example from my pinhole camera:. You can get a pinhole effect from any camera that has a detachable lens. The easiest way is to purchase a custom pinhole lens for your camera. Holga makes a pinhole lens for Canon and Nikon mounts. If you want to be creative, you can also drill a small hole in a body cap. This method is definitely less work. I recommend building your own pinhole camera and developing negatives from black and white photo paper.
Using your SLR is possible — you just need to get a body cap and drill a small hole.
