I recently got some old Kodalith and have been playing with it to see what I need to do to make it work. First, the attachment is my results so far, and here are the specifics:

Exposure ISO 6 + 4 stops
Developer Ilford DD-X 1:4, 3 minutes

Looks to me like the thing is over exposed (black case and pens have no detail, white marble background is medium gray) but what do you think about the falloff? While the white marble background is gray, the white stars on the pen tops is indeed white (and in real life is a brighter white than the background). I should note that this is scanned in with no editing other than a little cropping.

I have the feeling it is the developer but that is what I have on hand right now. Suggestions?
