Well, it may not be "all about the negative" but it is surely a lot about the negative, which is why I think that a sound understanding the sensitometry of negative making and print making will make your work a lot easier save youy both time and money.

And I agree with Michael about the Dick Arentz book. Although some may object to the heavy dose of sensitometry I don't think there is any doubt but that it is the most compleete book on Pt/Pd printing out there. The book Carl Weese did with B&S is also a very good reference.

BTW, Dick is currently in the final stages of a revisioni of his book and I think it should be coming out later this year. I did an appendix on UV light for the book and use quite a bit of sensitometry in comparing the results from different light sources.
