    Donald, you're on the borderline between English and Greek with that post -- I *think* I understand what you're doing there, basically adding timers to the outputs of the timer, but that really doesn't help that much with a Gralab, because I have to reset the original interval for each exposure, while a simple switch would serve to trigger the electronic timers you suggest (I think). Time-o-Lite timers reset themselves after each run (the motor works against a spring, which pushes the hand backward until it hits the stop when the timer shuts off at the end of an exposure -- you set the exposure time by moving the stop), which would be a great convenience if either a) printing a whole roll of film to the same settings (which used to be a routine operation), or b) printing many copies of the same negative (also a routine operation at one time).
    Photography has always fascinated me -- as a child, simply for the magic of capturing an image onto glossy paper with a little box, but as an adult because of the unique juxtaposition of science and art -- the physics of optics, the mechanics of the camera, the chemistry of film and developer, alongside the art in seeing, composing, exposing, processing and printing.

    Yes, you are correct. I was thinking of a purely electrical timer rather then a mechanical/electrical timer. My suggestions would work with a purely electrical timer to control two outputs and two sequences.
    Art is a step from what is obvious and well-known toward what is arcane and concealed.
