Building a 20×24 Camera – Part 3

We’ve made some progress on our build of a 20×24″ view camera. We put together the foam-core bellows using a healthy amount of matte gaffer tape, and did a test fit to the front and back standards. We started putting together the PVC pipe extension rail system, and we’ve got a whole host of small issues that will need addressing as the camera progresses. Excited about the prospect of having a working view camera, we attached the Fujinon-C 600mm lens to a piece of foam-core using the remaining gaffer tape, and made a makeshift ground glass from six sheets of tracing paper taped together, and had ourselves a proof-of-concept working 20×24 view camera! Some shots below (please excuse the focus/exposure of these snapshots!);

Building a 20×24 Camera – Part 4

We’re making good progress on our 20×24 camera. We’re reaching the final stages as we put together our focusing screen (clear perspex with a frosted film), made up a lens mount and attached it to the front face, and trimmed down our bellows slightly to allow better movement. Piotr designed both the lens mount and the cam locks for the film holder in the computer using a 3d program called Modo, then printed them out on his brand new 3d printer – a Makerbot Replicator 2. We gave a coat of matte black paint to the lens mount, added some felt to trap any stray light and it was ready to go.

Building a 20×24 camera – Part 2

My friend Piotr Stopniak and I started work on our 20″ x 24″ ultra large format (ULF) view camera today. It will be made from plywood, pine and foam-core card. We’re going to build a rail system using PVC pipe to allow the simple box-within-a-box design to expand and contract, giving us focus control.

Building a 20×24 camera – Part 1

As a collaboration with my good friend and fellow photographer Piotr Stopniak, we’re building a 20″ x 24″ ultra large format view camera for my next big photo project. Piotr is a Cgi/3d artist, and he was able to put together a 3d model of our design. It was a great way of nutting out what ideas were going to work and what wasn’t, and to make sure that everything would fit together properly when we go to make the final camera (provided we cut everything to spec). The idea was to make a working 20×24 camera that was simple, easy to build and relatively light. We didn’t need movements other than focus, so that helped to keep the design simple.

The front and back standards are to be made from pine frames with plywood sides, with the back standard deep enough to hold the film holder and something to hold the film holder in tightly. The main bellows are to be made from matte black foam-core cardboard, and will be able to extend and contract by using a simple box within a box design, where one box is ever so slightly bigger than the other. A simple loose material bellows will also cover the seam of the two boxes to eliminate any potential light leaks.

A rail system (similar to the box system for the bellows) will be employed to allow the camera to focus, by using PVC pipes, one inside the other and clamped to the base of each standard.

The ground glass will be a removable wooden frame with a frosted perspex sheet to allow focus.

We have a nice Fujinon-C 600mm lens to go on the front, and a very nice 20×24 film holder to go in the camera as made by Sandy King at S&S Film Holders. (Thanks Sandy!)

Here are some screenshots of the model of the camera.
