John- I haven't heard anyone in this thread talking about going into a Zone System twilight zone of endless metering before taking an exposure. Three or four readings are all that's needed in a tough situation, one or two in an easy one. Of course, knowing how to read a scene is a big help to know what to point the meter at in the first place. But you can scan a scene, pick out what you want to be the brightest highlight with detail, the darkest shadow with detail, note the range of stops, and calculate your exposure and development scheme based on the range. That's of course assuming you're trying for a 'fine art' landscape shot where that kind of tonal placement is critical. If you're shooting fast moving action, get a good incident reading and play Ron Popeil with the rotisserie oven - set it and forget it. Just keep aware of changing lighting conditions to know when to take another reading.
