Split development, trying to understand

[Sparky]

Why don't you try more traditional split toning - if that's what you're going for...? Try inducing a split vis-a-vis Rudman's published bleach-and-redev method in selenium...? I think it would be easier and a whole lot more controllable. Just a thought.

When I tried the carbonate test I took a piece of paper
and processed it with the lights on in a pretty strong solution
of Sodium Carbonate. It did actually take on some tone but it
looked more like paper looks if you just leave it out in the
light for awhile.

Some papers are indicated to contain small amounts
of developer in the super coats. Arista's EDU Ultra
Graded RC is the only Graded paper I'm aware of
which claims developer in the emulsion. Yet it
does require the usual processing. Dan
