i've read this a few times, but still can't understand what it means :\
which would yield more info (range) when scanned (same scene, same
exposure, same lens), slide or neg (and does it makes any difference for
color vs. chromogenic vs b/w?) thanks. btw, is kchrome less tolerant of
exposure error vs. regular chromes? and why is there "chrome" in
there? feel free to point me to websites for being very curious <g>
ob-OM-c: spent a roll (w/ and w/o PL) using 28 and 50mm zuiks shooting
fall colors hour prior sunset (lovely warm glow, almost no smog! what
a miracle...and quarter moon was perfectly positioned in the sky; full use
of PL to darken the skies there and saturate the leaves)
