Featured on Instructables!

The Easy 35 #pinhole camera was featured on Instructables last week as a staff pick!

It’s also in the Photography Contest but the voting closes 27 Aug – if you see this in time, a vote would be appreciated – over to http://www.instructables.com/id/Easy-35-3D-Printed-Pinhole-Camera/ for that – the voting button is at the upper right next to the medal icon.

If you haven’t seen the Instructables website yet, there’s an amazing lot of how-tos for an amazing array of subjects from an amazing number of people.  Lots of camera projects in there!

Pinhole Dreaming

Google has a very interesting project called Deep Dream, a sophisticated neural AI (artificial intelligence) program that looks for buildings, cars, dogs, birds, what-have-you in images. We can instantly process and recognize a dog or cat or bird without having them sprout all over our field of view, but pattern matching is difficult for computers. All I can say is the results are hallucinogenic and somewhat disturbing but at the same time, fascinating.

I ran my Loch Lomond pinhole photograph through Deep Dream and got this:

After Google Deep Dream processing.

Wow.  I never saw these when I took the picture.  Maybe I need new Google Glasses.

Easy 35 Release

The Easy 35 pinhole camera has now been published! If you want one and don’t have a 3D printer, you can use 3D Hubs or wait for someone to produce it on eBay or Etsy.

I wanted to create a new 3D printed pinhole camera that anyone with access to a 3D printer can make. The Easy 35 camera satisfies my goals of fast to print, cheap, and easy to make. Such a camera will appeal both to photographers and to educators wanting to teach principles of photography to youths. Based on 35mm film, the Easy 35 can be printed in half the time of a Flyer 6×6 and needs just a pinhole to assemble (at a bare minimum). A rubber band secures the top and black tape is used as the shutter.

The Easy 35 body is printed as one piece, incorporating the film chambers, rails, internal light baffles, and pinhole mount.  Such a camera is only possible with a 3D printer, since it cannot be done in one piece with conventional manufacturing techniques.  

Several copies can be printed at once on any 3D printer in black ABS or PLA.  Pinholes can be purchased or made with a needle and foil, and glued in or retained with an O-ring.

The Easy 35 camera is released in the spirit of open source, using the Creative Commons CC-BY-SA 4.0 license, meaning anyone is free to make them or even sell them, as long as attribution is given to the designer and any remixes or derivations are shared alike.  The Easy 35 camera is or will shortly be available on YouMagine, Pinshape, and Thingiverse.

Details on the Easy 35 camera can be found on www.pinholeprinted.com (in Products).

Easy 35 Pinhole


If you want a rugged, simple, compact 35mm pinhole camera with almost nothing to go wrong, the Easy 35 is for you.  The camera is open source (CC by SA) and can be made by anyone with attribution and any improvements must be shared alike.

There’s only one absolutely required part and that’s the pinhole pictured here.  You can make your own with foil or thin metal if you like to experiment with film and have your own B&W processing gear.

However, if you’re looking for the sharpest image and wanting to use a smartphone to meter your exposures, you need a 0.2mm pinhole.

The Easy 35 is designed to take thin flat 20mm pinhole discs, held in by an o-ring (optional) or glue.  19mm (3/4″) can be used but will need centering as you install it.  Larger discs will need to be trimmed around the edge with scissors to fit.

If you use a mounted pinhole, the mount is thick, and the o-ring may not fit if you use one.  In this case, the edges of the mount will need to be beveled with sandpaper or a file until the o-ring will fit.

Right now, you can find the pinhole at eBay, but this link may become obsolete.  Documentation and sources are maintained at pinholeprinted.com/support/easy35.
