    Remotely firing a shutter - how to ?

    Hi folks.

    I need a way to remotely trigger a Copal 3 or Ilex 5 shutters a fair distance from where I will be standing (say a 100 ft or more?). A mechanical timer/trigger won't do as the triggering needs to be on-demand.

    Any suggestions?

    Thanks.

    But beware of the dark slide.

    Try looking for the remote triggers used for game or wildlife shots - essentially an RF or IR trigger circuit with a solenoid to physically activate the shutter. You may need to "creatively adapt" the usual thing to work a long conventional shutter release cable.

    Buy a cheap radio controlled toy at Radio Shack, strip it and use the actuator to trip the shutter.

    get someone to stand next to it and fire it for you. semaphore will do the rest.

    Shutters that do not require much force for tripping can be actuated by a solenoid from an old press camera. These solenoids can apply more force if energized by the charge on a suitable capacitor at a higher voltage than originally used.

    Mables, and a good aim

    JW had it right - drag someone with you and have them trigger the shutter for you.

    Kevin: nice one!

    I use to have an ex-Amiralty Automatic Dial Recording Camera made by Shackman. It had a solenoid-actuated Prontor Press shutter. Big hint there, I think.

    So part of the solution is a solenoid that pushes when actuated plus mounting bracketry.

    The second part is a radio device that closes a circuit when it receives a signal. I have a Kenlock R77 transmitter-receiver pair that I used to use to trigger a cine camera remotely.

    And the final bit is, yes, a press shutter.

    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.

    Good luck, have fun,

    Dan
