I must say, the Polaroid comment is very good, one I hadn't thought about, but like Bill says, makes a lot of sense. I've seen it in action. I wonder if people (and I'm not calling any names here) who are adamantly against the kind of workflow I outlined WRT digital cameras are/were also against the use of Polaroids for figuring out the correct exposure (although I guess even then, where Polas came in handy the most was in a studio setup with tons of lights & flash action were also on the table, and may not be as applicable in field photography scenarios, which is what I'm really all about).
Again, I can't thank everybody who is contributing to this thread enough. Even if I don't respond to every post, I'm reading it and trying my best to absorb it.
I've already started carrying around the Luna Pro on my shoots :-)
