    Re: Filter on Sinar shutter and for 3 color separation negatives

    I've purchased a lot of Kodak Wratten filters and I think I will just hold each in front of the lens for multiple exposures . This will minimize the move of the camera during multiple exposures.

    It's easier than that.

    Mark off five square areas out of a long section of black card.
    Cut out three of the middle areas leaving the first and fifth areas (at the ends) uncut.
    Glue / tape the three Wratten filters onto the card so one covers holes #2, #3 & #4.
    Use black card to make a long rectangular tube in which the above mentioned long card can slide.
    Have a solid stop at the bottom otherwise the long card will fall to the ground.
    At the top of the tube there should be a round hole that will slide over your lens or attach to a filter ring.
    Focus, compose, stop down as normal.
    Set your shutter speed to something longish like 1/2 second.
    Insert the long card to the first uncut area covers your lens.
    Release the shutter.
    Drop the card.
    As the card falls the film will be exposed one at a time by each of the filters.
    When the card hits the bottom the final blank area will cover your lens.
    Your shutter will close at the end of the set exposure time (1/2 second).
    You have just used gravity to make a tricolor exposure with a Harris Shutter.

    If I understand correctly, the result would be only one negative with three multiple exposures through three filters? My purpose is to make three separate negatives, each through one filter.

    OK, that is different. Sorry I didn't remember that detail from your original posting.
    Then do this: http://users6.nofeehost.com/gepanpag/33_b.jpg

    What a Harris Shutter does is capture a sense of motion since each portion of the one negative is exposed a moment in time after the prior one. This works for leaves moving, water flowing, traffic, etc.

    I don't do color but I thought the dye transfer materials were no longer available.
