    They, depending on the paper you are using, allow you to center or compose the image on the photopaper without exposing the paper -- basically safelights for your enlarger.

    Most photo paper is not sensitive to amber/orange light. Some other material such as litho film and some photo paper is not sensitive to red light.

    At least with LF landscape, a bad day of photography can still be a good day of exercise.

    Speaking of the under lens filter...
    Does anyone know of a source of the red plastic filter material?
    The filter for my enlarger is missing the red filter element and I would like to replace it, if possible.
    All I need is a piece probably less than 3 inches square.

    It is for a Durst L1000.

    The Kodak color printing filter looks like it might work, but I don't need a piece that big.
    I'm also being cheap on this repair since it is not a "have to fix" problem.

    Would a Cokin or Lee red filtr do the job ?
    Failing that, contact Edmund Optics and see if they have a standard product line to offer.

    In all my years of printing, I've never used the red filters attached to many enlargers. I never quite saw the point.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    It might, as long as I could grind it to drop into the round holder.

    I don't use the red filter much on my other enlarger. But once in a while I have, so I figure why not get it repaired.
    But because it is not something that I use often, it is low priority = cheap fix.

    They might come in handy for exposing more than one neg onto a piece of paper and one only has one enlarger. Or perhaps rechecking focus during exposure/burning. But they are a low-priority item for most people.
    At least with LF landscape, a bad day of photography can still be a good day of exercise.
