With the digital, I had to return to my old slide shooting habits. I mostly use CW metering, as the Matrix is somewhat unpredictable even on a (nonpentax) body using state-of-the-art RGB CCD in the viewfinder (I never did believe the advertisement <g>), especially in classic high-contrast situations with lot of dark background (church wedding, concert,...). The gurus always said - for slides, meter upwards. Meaning get more of the sky in frame for metering, as the slide is better just a bit underexposed (=~ properly exposed). For negatives, meter downward (as negs are more safely overexposed). With digital, I use CW metering a lot, in the more difficult situations, and either meter off a surrogate subject (e.g. grass), or include more of the highlights in the metering area. Best, take a day off and try metering with CW - it has to be learned as everything, it's not just "CW metering underexposes". That's a nonsense. It really depends what and how you meter. CW metering needs some brain, but not that much. With digital, the learning curve is quick.
