    Split Grade: Does order matter?

    Let's say I have worked up a print the way I like it and I printed split grade with 0 and 5 filters.

    Now it's time to make my final prints. Say I want to make two more prints: 1 for toning and framing one to keep in my folder as reference.

    I print the first print with the 0 filter then the 5 filter. When I make the second print, the 5 is already in the enlarger. It just makes sense to print the 5 filter first then change to the 0 filter. There's a lot less fumbling around in the dark that way.

    Will printing the filters in a different order make a difference in how the final print comes out?

    Probably not. Unless there are issues about accuracy of timing, or reciprocity.

    By that I mean that if your exposure times are so short as to make it hard to maintain consistency, then you might see differences.

    Or, if the light levels are so low as to require very long exposures, there might be inconsistent results due to reciprocity failure.

    If the times for both filters are identical and your filter for grade 2.5 is exactly in between 0 and 5 you will also produce an identical result only using a single filter. It has been shown more than once. E.g. In Davis, Beyond the Zone System, Fourth Edition, pp. 158, 159. Splitting is just another way to get to the right filtration (not considering dodging and burning).

    No difference at all; I've tried it. Just make sure you're consistent in your timing between exposure and development; you'll probably see a difference if you expose the two grades an hour apart and then immediately develop because the paper slowly loses its exposure.

    With a little math+experimentation and assuming you're printing uniformly (i.e. no dodges or burns that are different in each grade) then you can do it as a single exposure at an intermediate grade. Not much point though unless you need to produce a lot of copies.

    Or your consistency may be higher. But I never said that...
    But as it is not possible to proof any kind of effect to be nonexistant as you can not test each and every conceivable variation and scenario where it might show, the discussion will probably never end.

    I use a two channel timer so it does matter for me. I have each channel preset for a specific filter time, my timer switches automatically.

    One curious exception I discovered: unregulated coldlight. During the exposure the intensity decreases as it heats above the set pre-warm temp.

    To me there is a difference. Maybe I just look long enough and hard enough to see a difference but my thought is you can make the whites black but you can't make the blacks white once you have layered them in. My approach is to darken the highlights not brighten the shadows.
