Mike,
No offense intended. I'm genuinely glad that you're having such good luck
with your cameras matching. And like you, I'm less than impressed with
150's and 170's.
But after almost as many years (22 for me) - - mostly as an EIC and/or
camera shader on trucks, but with some recently with pro-sumer cameras like
the ones you mention - - my experience couldn't be more different. I'd
disagree almost in a blanket way with your statement that "white balanced
identical make cameras should always match" for pro-sumer automatic
cameras. The main problem is that you can't get to all the adjustments
that you need to get to. The Panasonic 100 may be the exception, BUT the
controls are all buried in menus so it's difficult, if not impossible to see
the changes you're making in anything close to real time. And don't even
get me started on the lack of controls for overall detail and skin tone
detail.
Specifically : when matching different brands of cameras, I'm struck by the
differences in the way low-end cameras handle color. Different color
matrices, varying gamma curves, and the plain ol' subjective setup of what
white "should" look like on a vectorscope all conspire to make the job
difficult. Add in the different ways the various brands treat exposure - -
different peak vs. averaging iris setups, the different points at which the
cameras choose to boost the gain, and ways each one "tracks" the black
balance throughout the boost stages - - all these factors just make me want
to scream.
Maybe I'm being too picky. But that's my take on it.
More later, if there's interest . . .
