I am assuming that when I take shots of a white towel, it should be focused optimally. I'll take those shots tomorrow.girod
1) Grey card, +2.5EV: the data are very near the right wall of the histogram; no clipping at all.
2) White point white towel test: a. at 0EV: the data are centered at the midtone (Zone V) b. +2EV: near the right wall, no clipping c. +2.3EV: clipping starts (only Green channel, No WB correction) d. +3.7EV: Clipped but 100% recovered with highlight slider (52/100) without banding at 100% viewing.
e. On Rawnalyze: without WB correction, the Green channel is clipped at +2.3; with WB correction, aRGB (1998) - NO clipping of all RGB channels upto +3.7EV
2) Black point white towel and skin tests: at (-)5EV, the data are in the left wall of the histogram, photo is black or dark with no details visible; after applying shadow recovery slider (100/100), the data and photo moved to Zone III to IV, some and very acceptable noise at 100% viewing.
