Want to make sure your shots rock? Needing boulder colors? Why it's sedimentary, my dear Watson. Okay I'll stop with the puns and go straight to the TIpster. Good luck and have a gneiss time!
DIY Pinholes are ripe with possibilities. It wouldn’t be much of a stretch to say that almost anything can be made into a pinhole. Perhaps that the challenge? Instructable user amuu rises up to the challenge and has attempted to create a pinhole made out of concrete. Here’s how he started out:
Now, make an inverse of the design made out of foam board.
Mix the cement, then pour!
Once the concrete has set the walls around the mold can be carefully pulled away and you can dig out the foam from the inside.
Smooth out the surface and the rough edges. Once it’s cleaned up, paint the insides with black paint to make it light tight!
Make the pinhole, shutter cover, and film winder.
Finally, load the film and shoot!
Let us know how you fare with your concrete pinhole. If you want more in-depth instruction, head on over for the original post in Instructables!
