[Leica] BESSA R3A or M7

[jkoplen at mindspring.com (Julian Koplen)]

I "know" pretty much what you know, but I lack the experience with incident
meters to see what would actually work out best for a series of slides.  I
understand your point about getting a proper reflective reading and then
keeping constant exposure within a given lighting situation.  I'm also aware
that if a major part of the subject detail is highlight (e.g., white bird),
then one might want to decrease the incident or middle grey exposure
recommendation by half to whole stop, especially for slide film.

I'm not a zonie, but I probably use the concepts when I meter light sand and
then open up a stop or stop-and-a-half from the meter recommendation.

Thanks very much for your input.

Julian

Not in my experience.   You can get constant slide density with
either reflective or incident, as long as you meter once, and
do not change the exposure as long as the light does not change.

Even with incident meters, you still need to use your judgment
to interpret the light in contrasty situations; in such situations
it takes a lot of experience with how your films/paper/digital sensors
respond to light  to decide where to place the meter.

For the most part, I prefer incident meters.  However, with media
with very narrow latitude in the highlights such as color slides or
digital sensors, I sometimes prefer reflective meters and always
check the "hot spots".    See Dan Cardish's recent allusion to
reflectance, summarily dismissed by Karen Nakamura.  It appeared
that people missed Dan's point, and Dan is too lazy to elaborate.  :-)

Also, if you do any sort of "zone system", reflective meters are
de rigueur, a must.  While not a great fan of Ansel Adams,
if they are good enough for him, they are good enough for me.   :-)

Make sure you learn to use any meter properly; reflective or incident.
WIth reflective, do not just point to the scene, line up the arrows and
shoot.  Yeah, yeah I know Ted and his KISS.  I am all for KISSing too,
but what he didn't tell you is that it takes a lifetime to know where to
point the  camera before you line up the arrows.   That's what I hate
about pros.  They make it look so darn easy and simple.  ;-)
At the very least, point the reflective meter at something "middle gray",
before you line up the arrows.

You can get excellent results with either reflective or incident.

Please excuse my ramblings, for I do not know what you do or
do not already know.   :-)

Cheers,

- Phong
