The other thing that he asserts is that we should always be able to print on grade 2 if we use the Zone System. I have heard this other places but I have heard if refuted. Even Adams said that some people consider grade as their "normal" grade. Since I switched to the Zone system, I have noticed that I generally used grades from 2-3.5. I have color enlarger in my darkroom so I can go down 1/8 grades. I am happy with the prints I have been producing with this. Also, if your negative is perfect, why would you need to dodge and burn which I use extensively. I like my prints so none of this really matters but I am rather curious on thoughts about all of this. I must keep in mind that my instructor says we should never crop and that the square is more difficult to compose.
