When I use the film I linked above I do not need to fog or contact print. it give a negative from a negative
and when I use ortho film (often bergger) I work like that:
1. I do a test strip
2. I select the good time and multiply by 5x (this factor depend on the film)
3. expose again with the x5 factor and do all the dodging and burning needed, in this case more is less.
4.develop in PQ
7. bleached in a dichromate / sulfuric acid solution
9. expose to light( what ever the timing ) till there is no sun on the film.
10. Clear in a sodium sulfite solution
12. Develop again , I use PQ @ diferent dilution to get the Dmax I need.
13. I don't need to fix
SO compare to the direct positive film It is quite longer and I use much more chemicals.
hope this help
