Hi Les,
When you place your shadow on Zone IV instead of Zone IV what are you rating your film at? Are you able to get a full EI out of the film this way or are you judging the zone I at .10 >b+f? This seems like excessive density for the film to handle and you to have to burn through. Ansel always talked about the LEAST amount of exposure necessary to record the shadow needed. I think that is correct. Pls don't think me impertinent as I am just trying to understand.
