[Leica] leicameter. how to use?

[firkin at ncable.net.au (Alastair Firkin)]

There are probably better ways, but "in general", I set it to the high 
range out doors, and low range indoors, take a reading and if the 
needle is at the extreme of the metering range, switch it across. 
Sometimes takes two readings, but they are usually identical when they 
"cross-over".

Remember that the reading angle is about equivalent to a 90mm lens, so 
you can preview the "spot" using the 90mm frame.

The "great" thing about the "outboard" meter is the speed. Without 
appearing to be preparing for a photo, you make a reading, set your 
exposure, now watch the "victim" fixing the focus with the lens tab and 
faster than ANY autofocus/auto exposure camera in the world, you raise 
frame and expose. Makes one feel almost HCB in stealth ;-)
