Response to "tonality" and "acutance"

Saint Ansel clearly indicates in his book "The Negative" that sharpness (actuance) should never be compromised regardless of grain size. I've started using Rodinal with my 6x4.5 and have had excellent results, I look forward to trying it with APX100 in 4x5. I propose this: Rent, buy, or borrow a 4x5 or 8x10 camera, shoot your favorite film and develope it in your favorite developer, use that photograph as your benchmark, you'll see micro-macro gradiations, tonality, and anything else you care to describe. It's simple folks- there's no substitute for square inches....
