Remotely firing a shutter - how to ?

[Ron Marshall]

I suppose that you could rig a radio-controlled solenoid to cock a cock-and-release shutter, but the job would be simpler with a press shutter.

No need to cock the shutter, unless he is planning to make multiple exposures on the same sheet of film.

Then again, Daniel might have the Binford 2000 automatic film-holder flipper/changer/magazine. Great product. The only drawback was the noise and smoke from the 5hp engine. Why they used a 2-cycle engine, I'll never know.

Is Binford still making the 2000 Ralph? I thought they discontinued it in the 70s.

You might take a look www.ledex.com. This is a solenoid maker with a very wide line. You would probably need two different types since the characteristics of the Copal 3 and Ilex 5 are very different. I would be surprised, though, if they can't furnish something that would do the job. I have seen several of their rotary solenoids working the shutters on big process cameras.

Here are the specs for a linear push solenoid, 0.5 Lb force, 10mm throw, $18:

A pull -solenoid is even better as it allows to be placed away from the direct contact with the shutter release lever (you can use a thread to link the lever to the solenoid placed where you have a good place for it). More freedom for the fiddle with it.

Or mount a push upside-down with a string attached.

"Or mount a push upside-down with a string attached."
Perhaps, if it doesn't create a strange momentum on the selenoid lever.

What about those air bulb shutter releases. I've seen them 50ft before. B&H has a 20 footer but if you looked around or bought some surgical tubing the length you needed, I'm sure you could get it to work. If you want really far control, 100+ yards, I'd go to a model airplane hobby shop. I'm sure those people could set you up.
Good luck,

Regarding air, which would be my recommendation in many cases, Daniel says he wants to work at 100 feet or more. 100 feet is about the outer limit for air releases and even then the shuttter has to be one that is fairly easy to release.
