So called Divided D-23 is ideal because it is the only developer I have found which doesn't have to be used as single shot in this process.
Richard Sullivan in his book, “The New Platinum Print”, says that a good diapositive is both over-exposed and underdeveloped so that it shows dark highlights and weak shadows. This is good information to implant in your mind as you learn this process. HL are controlled by exposure,and shadows by development.
Using the diapositive to make the new negative is easier than making a print, IF YOU MADE A GOOD DIAPOSITIVE! A good diapositive will contain all the necessary information so that a negative can be printed at any desired contrast. Don’t forget that in this case you print for the shadows (the thinner areas of the negative), and alter the highlights with development. You must also remember, that you’re making a negative, not an inter-positive. This new negative will have contrast, not be flat like the inter-positive.
AS Franklin Jordan said “I’ll take your word for how dumb you are, but even at that, you can learn to make a good copy negative in one evening.”
Good Luck! and don't give up easily.
