How-To: Make a Pinhole
Since we are almost a month away from Pinhole Photography Day. I'm gonna share a series of articles dedicated to the design and construction of pinhole cameras. I'll try to explain how to use Mr. Pinhole's website to design a camera, and I'll give some ideas to make a pinhole camera using things you might already have at home.
Disclaimer: I'll try to simplify everything as much as I can. No Math! In case somebody is interested in more specific content, I'll add the best resources I've found.
The first step is to make a pinhole or buy one, but I encourage everybody to make their own, considering how easy it is. I recommend using different pins or needles to get an idea of the different sizes you can create. Also, make a few. It takes practice to create a good pinhole (you can get at least 9 pieces from a single can.) Remember, Practice makes perfect! And your camera is only gonna be as good as your pinhole.
- Be careful. The aluminum square can easily cut your fingers. I recommend adding tape to the borders before making the pinhole, just as a safety measure.
- If you can't push your pin, you can use a cork as a handle like the one I have here.
- Soda/ beer can
- Sewing pin
- Sandpaper ( I use 220 grit)
- Self-healing cutting mat or something to protect the table.
- Cut the can into squares. They don't need to be in a specific size. I recommend at least 3cm x 3cm
- Make a hole in the center of the square applying even pressure and keeping the needle perpendicular to the table. Do not push hard. You want to use just the tip of the pin to get smaller pinholes.
- Once you scan all of them, check which ones are good to use. In my case, only 3 are circular enough to create a photograph without distortion. (Don't expect perfect circles, but as close as a circle as you can get) Full-Size Image
- Repeat for each pinhole, and don't forget to write the size in each square. You'll need the information later to decide which pinhole will work better for your camera and decide exposure times more accurately.
Congratulations! you have made your own pinhole.
