    Hi,

    I am heading to this forum again for a wonder about ilfochrmome filtering.
    I use a color head enlarger (Meopta 6a) which is toped at 200 in C, Y and Magenta and
    the ilfochrome filters are toped at 50.

    A simple rule tells me that:
    5 in ilfochrome is equal to 20 on my enlarger.
    10 in ilfochrome is equal to 40 on my enlarger.
    And so on...


    Here is my wonder:

    Filtering with the head seems denser that it is with Ilfochrome Filters.

    For filters I do it bellow the lens. Might it be the reason?
