Hi,
I am about to embark on making 16x20 enlarged negatives from 8x10 for Pt/Pd printing.
I am using regular panchromatic films for making interpositive and ortho films for enlarged negative both processed in a pyro developer. I did read Bob Herbst article on it got the just of it.
I am trying to find out what sort of films would be suitable for making interpostives based on its characteristics. Simply because I am thinking of using more economical films rather than Tri-X or Tmax 100.
Also, is there any advantage of using pryo developer in this process? That is what Bob Herbst uses. I am also wondering if I can use, say, Pyrocat for this.
Is there books or articles that I can read to get more understanding of this issue? Any suggestions will be appreciated.
Warmly,
Tsuyoshi
