    I am printing colour for the first time and I am having trouble with getting it right. It is coming out Magenta! I am using a colour enlarger. I applied the filters settings of what one site said (5 magenta, 5 yellow, another said 1 cyan as optional), and it hasn't worked. I am using RA4 process. Please help!

    Thanks a million to whoever responds.

    Use the opposite of magenta. Why use filters? When i get my color neg films dont i ask them not to use cc filters. i say this because kodak gold 200 has turned out blue when they do this. IMHO, its better without filters.

    If the print is: too magenta- add magenta. Too yellow- add yellow. Too blue- subtract blue. Too green- subtract magenta. Too red- add yellow and magenta. Too cyan- subtract magenta and yellow. And, also, I think 5y 5m seems pretty low to start. I usually start around like 30y 40m or 45y 55m. But its all dependent on your paper, enlarger, chemicals, film, etc...

    Like he said.

    Go to the Kodak website and download the tech info for one of the papers. It should have a little chart saying the same thing.

    One unit probably equals 10 units of filtration. Normally, the filtration on a color enlarger should go up to around 170. So if you are using 5M and 5Y, it is probably really 50 of each, and close to normal. Just add another few units of M.

    If you use no filters (just a bare light source), chances are you'll get absolutely hideous colors; color film and paper are designed so that filtration is necessary to get good color, at least as a general rule. If you're using a photofinisher and ask for "no filters," they almost certainly are using filters (or are printing digitally), but they might switch off some of their computerized corrections that try to match the color on a frame-by-frame basis and that will get confused by scenes with unusual colors (say, a full-body shot of a single person against a bright orange wall).

    Then your enlarger is calibrated in something other than Kodak's units -- or maybe the filtration scale is marked in 10x units (as in, a reading of "5" on your scale should be read as "50"). In any event, the suggested starting points that are sometimes delivered with paper or that you'll find in manuals, books, Web sites, and so on are just that -- starting points. You'll need to adjust your print to get good color.

    One helpful procedure is to create a test print with the help of a test printing easel. These easels enable you to print anywhere from four to twelve or more images on one sheet of paper. Begin by composing and focusing your photo using the easel on which you want to print. Then swap in your test-print easel, re-focus, but do not adjust the head height. Find a part of the print with a good selection of colors, ideally including something fairly neutral. Begin making test exposures in each of the frames of the test-print easel, but vary the filtration settings and/or exposure you use in a systematic way. When you process the print, you'll have the same section of your main print repeated again and again, but with different color casts. Ideally, one of them will be dead on, but chances are you'll just have one that's better than the others, and you'll be able to see how to adjust it from there. If your initial guess for time or filtration is way off, you might need to repeat this process.

    Personally, I use a test-print easel that enables me to put eight exposures on one 8x10-inch sheet of paper. I use two of these frames for exposure tests (subdividing each one, so I can test four exposure times). For the remaining six frames, I vary the cyan, magenta, and yellow filtration up and down by 10 or 15 points. Obviously, careful record-keeping during a print session is critical if this procedure is to do any good. Be sure to write down your planned sequence of filtration/exposure settings, or the starting point and how you plan to vary filtration and exposure.

    Voided Ramone made a typo. If the print is to blue, subtract yellow.
