Converting Split Grade times back into single grade?

The last time I did this I wasted a day finding out that fibre based photographic paper changes size depending on how wet it is. The slightly out of register images I got might have been "art" but they weren't the subtle split grades I was looking for.

So it doesn't work?

When you give the Emmerman process a try use something that does not change size with moisture content. Hint: RC paper.

Drew.. have to disagree_**** I don't see any sense in mixing B&G light or Y&M, as this simply created neutral density,***

Not so - If you add a third component then you get neutral density... ie 10 cyan, 10 magenta 20 yellow.. you will have 10 units of ND or 1/3 stop with 10 yellow.

Magenta and Yellow filters are not equal and will darken or lighten a print differently.. with Magenta being the big Kahoona...

Bob, as I'm sure you know, the reason for the mixture is to change contrast without effecting exposure, although I must admit it doesn't always work in practice.

One's percieved assessment of the target tone can be affected by the surrounding values. A properly constructed table of filter values will print the same value from each coordinate.
