Rob,

What I'm thinking was a case where medium grey is overexposed 2 stops, then 14 stops DR will give room for 7 stops below, reaching down to pure black. The 14.5 stops gives you 2.25 stops leeway above and below the grey scale.

LOL, I understand, but when you expose to the right to preserve highlights while maximizing shadow detail, you are using the zone system ala digital age.
