EV is a feature on my LX I haven't used yet because I'm not sure I fully
understand it. Am I correct in conceptualizing it thus?
In terms of the match needle in my K1000, a bright scene (snow, sand, etc.)
makes the needle ride high, which is the camera's way of telling you
to stop down. You're free to ignore that advice, and in this case you
should. With autoexposure the camera makes the choice, so you dial in
a positive EV as a way of "forcing the needle back up," as it were.
The opposite is true for under-lit scenes, so you use negative EV.
Is that close to the mark, or am I full of it?
