Question abotut film processing
I am finally understanding the differnt way to develop BW film but here is my question. What do you want to say go N-1 on a very contrasty scene? Does it ahve to have 7 stops on tone or more? For N+1 is the scene is 3-4 I will add some time to the development but leave the ISO the same which turns out pretty good.
Now when they say N-1 I will overexpose the film a bit ISO 100 rated at 64 to suport the shadow and make sure the mids to not turn to mud when I pull the time back on processing but how much time is N-1? 50 less or 100% less than normal. For example say it is 10 minutes for normal processing would N-1 be 5 minutes?
