Keith, how do you figure exposures using the Leica - does it have a built-in system of metering?
I ask, because though I find the Nikon Matrix very, very good, my recent shoot has led me to wonder if it may be better using an incident light meter again. I'm not sure how digital capture will really react to such a reading - I did try it out when I got my first digi camera (the D200 that I still use a lot) but though I felt it was an accurate way (hand metering), I didn't, at the time, have enough experience with Matrix to know just how generally good Matrix is, and so I suppose I gave some bias in favour of the incident light meter's possible superiority.
My thinking has been rather confused by the 'full exposure is best' philosophy I find in these parts... conflicts with the expose for the highlights concept. Yeah, noise in shadows is a possibility, but often highlights are more important and I add noise a lot too, intentionally, but that's a different call!
