Today I ordered 100g of CD4, the P-Phenylenediamine derivate that is used in C41 processed films and that I also mix in my homemade Caffcol.
I am wondering now if the 5% solution I need is prepared putting, for instance, 5 g in 100g total solution weight. In the absence of any advise, I am assuming so. And if it is right, this also means that the 20 ml/liter of a 5% solution I am using now only has 1g of CD4 and develops, for sure, more than one roll. In this particular it should be comparable to the 20 or more from the Tetenal kit. But it is still too soon to make this calculations.
I haven't made photos today, I leave you with one from yesterday
