February Pinhole Camera

This month is a simple build. I constructed the camera from a metal watch box. Placed the pinhole in the lid and used a simple tape shutter. I folded a 7 inch square of photo paper to fit inside the cube.

I was surprised how the image was captured inside the cube, I was expecting more distortion up the sides. Cutting the paper to fit in the cube was a little time consuming. Overall I was overall happy with the results and this could be an interesting start to a larger project.

January Pinhole Camera

8 sided Christmas tin

Came across this in the Dollar Store and thought it would make an interesting camera. I am going to put a pinhole in each of the sides and a circular core in the center to hold a 3.5 x 6 inch strip of photo paper.

Holes drilled in each side of the tin.
Hole drilled in the bottom for the tripod mount and to attach the central core.
Central core made from a piece cut from a plastic caulking tube.
A piece of wood cut to fit inside the tube. It has a 5/16 in hole drilled to accept the T nut.

The T nut is driven through the bottom of the can and into the hole in the center core.

Painting the interior of the camera black. I used two coats of flat acrylic paint.
Making the pinholes out of a beer can. I calculated the focal length to be 35mm and a .26mm pinhole was required. The camera will be f135.
Mounted a pinhole in each of the 8 sides of the camera.

I am glad that I built the 8 sided camera but it is not something I will use regularly. The camera is really fiddly to load and I don’t find the resulting images all that exciting.

Digital Pinhole

Over the years I have made or purchased countless pinhole cameras. What they all have in common is that they recorded the image either onto film or photographic paper. I had always hoped that a pinhole lens on a digital camera would be a viable option, but unfortunately, I have never been satisfied with the results. Here are four different options that I have tried for my Olympus Micro 4/3 camera.

All of the photographs were taken under the same conditions with only the levels adjusted in Photoshop.

Pinhole Body Cap

Quite simple. A body cap with a hole drilled in it and a pinhole put in place.

Pinhole Rising

I bought this commercially made pinhole body cap from a local camera store. It is a body cap with a metal insert that has the pinhole drilled in it.

Wanderlust Pinwide.

I got this one by supporting the original Kickstarter campaign. Made of plastic. It extends well into the camera body and is very close to the sensor.

Thingyfy Pinhole Pro S

Well made of metal and like the Pinwide, extends well into the camera body.

Final Thoughts

The Pinhole body cap produced images that are sharper than the Rising Pinhole.

The Wanderlust Pinwide has the widest field of view with some vignetting at the corners. In my opinion it is the sharpest of all 4 lenses.

Both the Pinwide and the Thingyfy show the yellow “blotch” in the upper right side of the image. The Pinwide exhibits this more than the Thingyfy. This “blotch” is caused by the angle at which the light hits the sensor. If the image is converted to black and white it is a non-issue.

All 4 of the lenses produce reasonable results in the Micro 4/3 format, but don’t produce the same image quality that can be had shooting film.

Arista Litho Film

I have been shooting Arista Ortho Litho Film 3.0 in my Zero Image 45 pinhole camera. I had been developing in Dektol 1:30 but found the contrast to be a little high. This time I exposed at an ISO of 3 and developed for 3 minutes in Dektol 1:10 with added Potassium Bromide as a restrainer. The images could have used more exposure but overall I am pleased with the results.
