Greetings,

My name is Kevin and I am a photographic artist in the GTA.

I was wondering if anyone could assist in building a shutter for my
shutter-less lens.
This of course would be a paid job.

I'm looking to start using a large format camera for an experimental
photographic process.
The problem is I don't have any shutters for my old barrel lenses.

There are shutters being made now called Packard shutters that are large
enough for my old giant lenses, but you can't adjust the shutter speed with
accuracy.
Because my lenses are so big, a focal plane shutter would need to be
mounted at the front of the lens.

https://en.wikipedia.org/wiki/Focal-plane_shutter

Here is an example of a dual curtain focal plane shutter which I was told
would work for my lenses.
Basically you have two springs holding back fabric vertically or
horizontally.
The front fabric curtain is closed/doesn't let light through and the rear
one is open.
After a microcontroller releases the front curtain, depending on the
desired shutter speed the second/rear curtain closes.

The design I was told to try to build is a bit different than the example
in the video.
Instead of a rolling mechanism to reel up the shutter fabric (which can
still be found in a big enough size), one would just use two extension
springs that pull on the shutter fabric (one for the front fabric/curtain,
and one for the rear fabric/curtain.

Some issues I'm thinking of are vibrations that will cause motion blur
during the estimated 1/2 to 1 second exposure and durability. Perhaps the
extension spring chosen can be just enough to move a light fabric across
the front of the lens. And as for durability, perhaps this shutter
mechanism can be 3d printed or made of lightweight wood.


If anyone can help build a durable version of this please contact me at
toyo8x10 at gmail.com.



Thanks for reading this.
I hope you are well and stay well.

Best Regards,
Kevin H.
