Custom Lensboards For A Large-Format Camera

Featured
Large-format cameras typically allow lenses to be interchanged by mounting each lens on a lensboard. If you have a lot of lenses, you need a lot of lensboards.... Beyond that, if you want to mount any of multiple lenses that have the same screw or bayonet mount, you shouldn't need a lensboard for each -- why not have just one lensboard with the appropriate mounting flange for your lenses?

This Instructable shows how to build your own high-quality wooden lensboards. We'll show a simpler construction that works for some large-format lenses, the standard construction, and a variant of the standard that provides an interchangeable mount accepting any of a wide range of lenses -- without the need to swap lensboards.

This instructable is the logical inverse of http://www.instructables.com/id/Large-Format-Adapter-For-Your-Mirrorless-Camera/ . There, a back was created to allow a mirrorless body to replace the film in a large-format camera. Here, you'll learn how to build a front lensboard, including a special type that allows any lens that could mount on a mirrorless body to mount on your large-format body. Why do this? Well, lenses designed for smaller formats will not cover a large format at infinity, but this adapter will allow you to use them as tilt/shift macro lenses -- and many will cover 4x5 at macro focus.

View camera's are getting to be kind of rare anymore. But I think they are fantastic. I majored in Photography at SIU , which is pretty close to where you are, and I spent an entire semester working with view cameras.

Something you might find interesting to try ---

I used to put photo paper in the film holders and shoot it like film. You need to experiment to get the speed right as the paper is much slower than film. To develop it you just process it like any print. Now that we have digital scanners you could take the print, which is actually a negative image and scan it and reverse it into a positive. Paper has different light properties than film so you might get some really interesting effects and its a lot cheaper than using film.

Interesting point. I exposed paper negatives that way long ago, but I never tried making high-resolution digital scans to print them. Film speed, tonal scale, and color sensitivity profiles for paper are very different from most films, but that could be a very interesting and relatively economical thing to try....
This is beautiful. You did a really good job with the constrution and documentation of this project. I adore large format photography, perhaps one-day i will have my own.
