Hans-Peter:

I always find that the more I shoot the less I need to meter.  The "sunny
16" rule is a good starting point.  Open up 3 stops for overcast or in the
shadow.  Using a hand-held meter a lot helps but practice guessing is most
important.  Leave your meter home and bracket your exposures and look to see
which works best.  Getting used to thinking about the light is what it is
all about.

A long time ago I shot news film for a TV station, before they all went to
portable videotape cameras.  I used a Sekonic studio deluxe incident meter
(which I still have, on its third movement!)  If I forgot and left it home
it didn't matter.  I usually encountered the same lighting conditions day
after day, and I shot every day.  I got to know how it looked in the reflex
viewfinder as you stopped down.  Once a cameraman who used an auto exposure
camera to shoot news film asked how I would measure exposure with the
incident meter when the light was on the camera.  I told him, "well, you
have f2.8 and 4".  Beyond a certain distance the light fell off too much for
the maximum aperture of that zoom lens.  It wasn't hard to tell which
aperture to use.

Hello,

I always admired those guys who are confident in reliably estimating
exposure
without using a meter, at least with negative film. Moreover, I consider
this
ability as a precondition to actually enjoy using a M2, M3 or M4. Of course
I
looked at the little tables that come with most films or that are shown in
older
books on photography, but looking up tables is more annoying than using a
handheld meter. Also, a have my fair share of experience in using the M6's
coupled meter. As a result I am now quite confident in guestimating exposure
indoor under artificial light and under the open sky.

Apparently the architects of public buildings, department stores, offices,
underground stations etc. follow certain engineering standards in lighting
which
usually result to something like a 1/60, f=1/2 with 400 ASA. Smaller offices
with lower ceiling and bright lights. are rather in the 1/60, F=1/4 range. A
living room or a pub may go down to 1/30 or 1/15 with f=1/1,4.

Under open sky conditions I apply the "sunny 16" rule (1/500" with f=1/11,
ASA
400). Depending on the clouds I may open the aperture by up to 4 stops. 1 or
2
hours after sunrise or until sunset, an additional correction by minus 1 or
2
stops seems to be necessary.

But I have problems to estimate exposure in narrow, shady streets and for
shadows in general. For a time I thought that a correction by minus 2 stops,
in
addition to the above, of course, would be the right approach, but to often
this
resulted in underexposure. Apparently, the indirect light depends to much on
facade colour, height of buildings.

I would therefore appreciate if I could share the experience of other
LUGgers,
particularly if there is someone who has a more systematic approach.
