    broke the red plastic, cam-shaped red slide for my rolleimatic enlarger.
    Can't remember what it is called but it allows me to focus without
    exposing my image. I anticipate that finding a replacement will be
    extremely difficult so I would like to cut out a new one.

    Question: is the red slide just lexan? acrylic? What would be suitable
    to use for an enlarger? And if possible, sources? In canada???

    I never got into the habit of using the red filter. Depending on the type of
    paper you use, it could fog the paper; definately if you use color paper.
    Unless you are using a very thick base paper, it shouldn't make much
    difference if you focus directly onto the easel. If you are concerned about
    the focus being different due to the thickness of the paper, focus on the
    backside of an old piece of the same thickness paper.

    If you are really set on replacing the filter, the material is not so
    important as the color or the optical quality. It must be of a particular
    color so that it doesn't fog the paper, and it should be of an optical
    quality that it won't distort the image.

  3. A Wratten 29 should work, but a piece of Rubylith will be cheaper. They
    do still make Rubylith, I'd hope -- but I have to admit I can't see why...
