It helps a lot, thanks very much. I'm getting basic exposure theory
review from a lot of angles, and it's just what I need! I'm also
reading the Kodak workshop book on Flash, Arthur Morris' book on bird
photography has a good chapter on exposure theory, and a bunch of
stuff I printed off the web. Changing camera systems like this is
really making me examine what I know! On my old system (Canon FT) I
had come to a lot of wrokable approaches pretty much trial & error
(lots of error) and intuition. But it was good glass.
I'm looking forward to getting back my first roll of Velvia with Snowy
Egrets, Pelicans, Black-necked Stilts and Terns! Then I will go back
to the same place and see if I can get better results based on what I
see, having shot that roll pretty much in the evaluative mode with
only a couple of compensations where they were obvious.
