    You should never use 3 filters for either color or B&W unless you want to use it as a neutral density to increase exposure time.
    That's precisely why I did use it. I prefer to have printing times in the 10-30s range, and in fact my enlarger's timer (built into the Philips PCS150 controller) has a minimum print time of 5s. Using the filtration I used, I got an exposure time of 15s. Removing all the cyan filtration would have gotten an exposure time of about 5s.

    FWIW, with this enlarger I generally need to use more than the 55 cyan filtration I mentioned in this example, since removing it would result in sub-5s print times. When doing color ringarounds I usually start with around 100C (and higher values for M and Y) and adjust exposure time and filtration as necessary. Even if I can, I don't usually bother removing "unnecessary" filtration unless my print times get above 30s or so; mucking with the dials once I've got things set to give me a good print just introduces more room for error. I'd rather wait another few seconds during exposure than have to redo a print because I mis-set some value.

    All of this just goes to illustrate my original point: Modern color papers are very fast.

    Ummm. Well, I just stop down one stop to f11 instead of f8. Or, I use the half click between 11 and 16 if needed. My normal exposure on my Beseler Dichro 45S is 10" at f8 - 16 depending on negative and print size, and my normal sizes range from 35mm to 4x5 enlarged up to 16x20.

    I know that currrent Endura color papers are about 1 stop faster than the Ektacolor Plus series which was about 1 stop faster than the Ektacolor 20 and Professional series.

    But, if it works for you, use it.
