Diy Large Format Shutter
Mounting this lens in a large format leaf shutter can be an expensive undertaking, and due to its size, the shutter options are somewhat limited. Because Im of dutch descent (thrifty, cheap, frugal), I took it upon myself to find an inexpensive solution to this particular problem This article shares the design for a working model of a reasonably fast 3d printable, scalable, and fully mechanical spring powered large format leaf shutter camera with flash sync.
This video shows how I made a servo controlled shutter, suitable for low speed film such as paper negatives or lith film. This is suitable for use with large format process lenses or home made... There's someone who has posted to the LF forum who made a leaf shutter electronically controlled by a servo motor and Arduino, with 3D printed parts.
Learn how I constructed a large format shutter for use with barrel lenses that provides a simple way to achieve a range of shutter speeds. This is a fully functional model of a leaf shutter for large format photography. It is completely mechanical and capable of exposures around 1/60 of a second (and probably a bit shorter).
I'm looking to find people that would be interested in teaming up to work on a project to build "electro-mechanical" rolling blind shutters for large format photography barrel lenses. To verify the concept I measured the shutter time using a photoelectric eye and an oscilloscope. The leading edge activates the switch while the trailing edge deactivates the switch.
I am now using one that I mounted in a Thorton-Pickard shutter for more than 8 years and it seem it will remain usable for quite a while. That is what I documented and described in its basic steps in this page. I've considered the lenscap on/lenscap off routine and the whole packard shutter ordeal, among other things, and they both have their advantages and disadvantages.
I'd like to hear a few suggestions as to what would be a good method for making time exposures without shaking the camera in the process. Any ideas?
