Having a camera with live-view is very cool. It's one of those features that grew on me, I had no idea how I was going to use it.
Back in the days of film, I'd look at a subject, determine how it was lit, back-lighting, side-lighting etc., and set my exposure accordingly. Many times I would bracket my exposure, that's when a photographer makes a few frames of a scene using different exposures. Maybe one the camera meter recommended, one over-exposing the scene and one underexposing the scene or a half stop over and a full stop over. So a roll of 36 exposure film could of have varying exposures of 12 photos on it.Live view show you exposure before and sometimes it's just great.
This photo of bananas on the window sill is a perfect example. I was sitting on the couch reading and glanced up into the kitchen. I noticed the bananas on the sill and how they were back-lite. The lines of light were very intriguing even sensuous.
I picked up the Canon G10 and looked at the screen in live-view. The exposure was set for the shadows and the hi-lights were blown out, rendered white. It's so much easier now to get what your looking for. Sometimes the right exposure is not the metered exposure.
