‘These images were taken today with three different pin hole cameras in Flatrock Nature Preserve, in Englewood, NJ. This is just on the backside of the Hudson River Palisades, i.e., just to the west of those cliffs. Each image was exposed for approximately fifty minutes during cloudy weather, and I manipulated them in GIMP, adding a bit of sepia toning.
This first image was taken with a coffee can camera, which produces a distorted perspective, although in this setting, it is not so pronounced: No straight lines in nature!
This image was taken with a box pin hole camera set about two feet above the water surface on a rock.
The last image, below, was done with a box pin hole and a tripod set up.

That’s a coelacanth, and some fruit. The barcodes got blown out, despite the shady day.

I was growing tired of wide-angle shots, so I constructed a third pinhole camera from a shoe box, cut to about one third of its length. Keeping the box lid intact at the end allowed me to easily construct a flip-up paper loader along the back of the camera box. It seems to be very effective at sealing the box, and I put in some tabs to hold the photo paper in place – no curved photo-plane this time. I improvised the usual tripod mount with scrap wood and a piece of hardware from Home Depot.
I cannibalized the aperture (0.3mm) from my wide-angle camera to use with this one, even though all the formulae indicate that a 0.45mm pinhole is optimal: I have new ones on order, but I couldn’t wait. Rushing again… With a focal length of 5-inches, the f-number is about 425.
My first attempt with the new box was a shot of the USS Ling taken from down near the water, a great shot of the rusting hulk of a submarine, but I noticed that the aperture didn’t seem to be properly fixed to the camera body. Sure enough, in the darkroom, I got an all black print. 😦 I had made a too big hole in the box so that when I taped the aperture holder over it, I didn’t quite close it. It was hard to tape on without bending the camera wall since the hole was almost the same size as the aperture holder. I fixed this by gluing a sheet of matting over the original hole, with a smaller hole punched in it, over which I taped the aperture holder. The thickness of the whole deal is so little that I don’t have to worry about vignetting the image.
After the repair, the camera worked great. Perhaps a little light leak showing in the upper part of the image, but that might just be the bright sky with tree shade.
And a nice gothic shot of our town hall shot with my 0.2mm camera.

Yesterday, I ventured into Manhattan to meet a friend for lunch down near where I used to work, and afterwords, we strolled over to the WTC Memorial, directly across from my old office. (Also from Century 21, where I bought a pair of Italian shoes. 🙂 ) I had been planning to take some pinhole shots, and the weather was good.
I had my 5″x7″ photo paper camera loaded and ready, and I set up my tripod for what was to be a one-minute exposure. Oops, no tripods allowed, I was informed by two policemen. I can see how they would need to have that rule to prevent the area from being clogged with photographers at their stations. Nevertheless, when they saw the nature of my equipment – clearly, I was not a professional doing commercial work – they looked the other way for sixty seconds, and I got this shot.
Over near the Santiago Calatrava PATH terminal, I took another shot, this time with my 0.2mm, 0.9″ pinhole using 3″x 3″ paper. I crouched down and held the camera in my lap for a thirty second exposure. Not tripods there, either! I like the spooky, Expressionist feel to this image.
