First, my DIY tripod mount was flimsy at best. While using the PinBox I soon noticed some difficulties. Yay! Now let’s go get some pinhole pitchas! I used the PinBox outside my condo building, at a nearby park with a large outdoor art sculpture, and at a well-known waterfall along the Cherohala Skyway. Channeling my inner MacGyver, I found my smartphone tripod attachment, mounted it on my tripod, and used it to clamp the PinBox onto the tripod. The little cardboard camera does not have a tripod mount.
PINBOX CAMERA HOW TO
However, I had one more problem to solve: how to mount the PinBox on my tripod. With the Pinhole Assist app, my tripod, and the loaded PinBox camera in hand, I thought I was ready to go. It will even work with your smartphone's timer to tell you when to close the shutter. Once you have selected the film you are using, it will add the needed exposure compensation to the given time.
Not only does it serve as a light meter, but it had a built-in database of films and their reciprocity failure calculations. Sure enough, I found lots of apps, but the one that seemed to be best is a paid app ($2.99) called Pinhole Assist. So, thinking that “There's an app for that!,” I checked App Store for some help. This all sounds quite complicated, and I felt like a fish out of water as a loaded my newly bicultural PinBox camera with a roll of Kosmo Foto Mono 100 (a b&w film I quite like). And if that isn’t enough, development times have to be shortened to preserve the highlights. With color films, not only will they need exposure compensation, they also will need filtration to compensate for color shifts. Fortunately, most films come with reciprocity failure information with instructions on how much exposure compensation the film needs. While every film is different, most films require extra exposure over what your meter indicates. Reciprocity failure is a film's inability to respond to very low levels of light. The answer lies with a certain film characteristic known as reciprocity failure. Simply taking the aperture size ( f200, for example) and then using either Sunny f16 or a light meter to calculate the exposure time will not work with pinhole photography. Second, calculating exposures can be very tricky. First, some way of keeping the pinhole camera rock-steady is essential, and this means a good tripod is essential. However, this comes at a price: long exposure times. Pinhole photographs can have an other-worldly look that can be quite attractive. Pinhole cameras are interesting not only because they can be made out of a box or even a can, but also because the small size of the aperture (the pinhole) creates deep depths of field. Put light sensitive film instead of drawing paper in a camera obscura and. Later, lenses were used to better focus the image, and the camera obscura was used a a drawing tool. It likely was by accident that in ancient times someone discovered how light, when passing through a small hole in a wall, will project an upside down image on an opposite wall. The idea of a pinhole camera reaches back to the very beginnings of photography. In case you don’t know, a pinhole camera is a camera that lets light in through a very small hole instead of a lens.
“Let’s build a pinhole camera,” I said as I took the package out of a cabinet.
Then came 2020, a global pandemic, sheltering in place, and time on my hands. Getting our house ready to sell and then moving to our downtown Chattanooga condo became priorities, and the little package was soon forgotten. However, when my PinBox arrived, I was crazy busy with putting on a school musical and sis not have time to even open the package. After all, a 120 film camera that you can build fairly easily from heavy card stock would a great project for students at the elementary school where I used to teach music. After viewing the Kickstarter video, I decided to give it a try. 3-D printed top and bottom winder keys are also supplied. The camera is assembled with school glue and quick-dry glue. The kit comes with precut and scored card stock and a precut aperture. PinBox is a DYI pinhole camera that uses 120 film. It was well over two years ago when I learned about Robert Hamm and his Hamm Camera's PinBox Kickstarter project.
