    I recently obtained a glass carrier to use in my D5500 4x5 Enlarger hoping that more uniform flat negatives would improve my prints. The glass part of the carrier is about 5x5" so a normal 4x5 neg will have to be masked. When I picked it up at KHB, Kevin said that users normally make their own masks. Now that I am working at it. I have a problem.
    If I put black card in between the glass plates they do not close properly, rather defeating the whole purpose.
    If I put the card material on the outside, the light bounces around the gaps made by the glass plates.

    Am I missing something? ...

    Just let the mask sit on the top. Will be fine.

    If you want to get real picky, make a 5x5 by taping some totally exposed and processed negs together with silver slide binding tape that is super thin. now cut a hole where you drop in a 4x5 neg.

    Before I made my 35mm one side glass, I used the 4x5 double glass with a mask on top and bottom outsides about 2mm bigger than the film image area. It was ok, but a pain to work with as the neg strip had to be oriented at an angle to clear the locating pins that were centered. They sell it as a universal glass carrier so 4 locating pins should be used to accomodate film strips.

    I had a similar issue and black masking tape worked for me. If your negative carrier doesn't rotate for horizontal and vertical prints, you'll have to print your verticals sideways...that's what I do.

    What's the problem? Why mask? I use a glass carrier
    with my B8 Omega 21/4 x 31/4. Smaller negatives are
    centered then printed. Dan

    1st time using glass carrier...

    Tim, what I have done for years is this: Buy some B/W sheet film, take one outside into the sun, develop it, it will be black. I then get a sheet of graph paper, measuring very exactly the size of the mask I need onto it, then I tape the film sheet to it and cut (with very very very sharp blade) through both film & paper from the paper side. This is probably the easiest & cheapest method. No problems with the neg carriers not closing! Once they're made, look after them & they'll last for years.
