    Go to http://www.rosco.com/uk/index.cfm

    and order a calcolour kit. It's a bunch of large colour filters. You can lay them over top of your contact printing glass and negative if you want to have some control over contrast.

    Oriental RC and FB paper is available in Grades 2, 3, and VC.

    Edit: VC is the way to go IMO. Recently I contact printed a negative as a Grade 3 on VC paper after having ruled out Grade 2. But after looking at the dry print I thought that it looked a little dull so I went back and reprinted it at Grade 3.5 and the dry print "popped."

    Sounds good. I will look into it when I'm not in a hurry like now

    Where in Dk are you located? Come visit, and I'll proberly be able to give you an enlarger to take back home...
    That is very kind of you!, but I live in Odense. I may take you up on the offer when I drive to Copenhagen some time.

    EDIT: Somehow I had gotten in my head that you ive in Cph. But now you know I live in Odense.

    dial in. If you are using a lightbulb, you could use a colored studio "gel" holder to safely
    space a sheet of colored polyester a distance from the light, or simply handhold it over the
    contact frame. Often you need a certain amt of high-contrast light, and a certain amt of
    low-contrast, determined by trial and error. It's called "split printing" and is actually quite
    easy once you have a little practice. In my experience the Oriental VC paper would be closer to Gr3 unfiltered, but it depends on just how "warm" your lightbulb is. The warmer
    or more yellow (lower K color temp), the lower the contrast.
    Ah, that explains it. The light would be the ugly pale stuff (only legal/currently in production light bulbs here...).

Grading is by contrast (i.e., contrast grades). Grading varies according to the type (wavelength) of light projected upon it, at least with VC papers. Most incandescent style enlargers rely on separate filters (yellows –> transmitting blues, and magentas –> transmitting greens) to achieve a contrast grade from hard (5) to soft (1), correspondingly.

    I believe a VC paper exposed to all wavelengths of light from an incandesent bulb without filtration will give you something like the equivalent of grade 2 contrast, which used to be considered neutral. Single grade papers, which you are unlikely to find as RC, will simply produce the contrast grade advertised, no matter the character of the light.
    Very useful info. Thanks!

    A small enlarger makes an excellent light source for contact printing. You get consistent exposure times and they usually have a place to mount the VC filters. I use an old Federal that packs up into its own case so space is less of an issue.

    Well - CPH is as far away as I can get....

    Oh god that is some trip. I've never been deeper into Jutland than Randers...

    Anyways, I actually might go ahead and get an enlarger. But will a 35mm one light up 14x17? Or do I need to go bigger.

    Yes, a dedicated 35mm enlarger's projected light will allow you to cover 14x17 on the baseboard.
