Density of ilfochrome filters vs color head
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?
