Camera obscura in less than 10 minutes.

A fun project to do with kids or adults. Project an image from outside, into a dark room simply by using a small opening in a covered window. I was reading a book about the history of photography with my wife and daughter, and upon mention of “camera obscura”, my daughter inquired about it. I thought it best to just demonstrate it. So this is what I came up with in less than 10 minutes 🤷🏻‍♂️. If you want to try it yourself, it’s easy to find simple instructions online. It’s really fun!

We used a small bathroom because it had the smallest window in the house, making it easier to cover, but you’d get better results in a larger room. You can also play with modifiers to create different sized “lenses” for better focus. I experimented with a toilet paper roll and a washer inserted into my business card. A smaller opening (aperture) offered more detail, but less light into the room. The image you see here are some trees in our backyard, part of our garage, and our neighbors house behind us. The image will be projected upside down on the wall. Give your eyes some time to adjust and enjoy your camera obscura.

Tip: If the projected image appears dark to your eyes, try using your phone to take a picture of it, as it will capture more light from the projection. You’ll get best results doing this on a bright sunny day. Give it a shot!
