Thanks for all of the feedback.(posted 8911 days ago)I've re-performed my film/meter exposure tests and (based on a densiometer) my meter is spot on for Delta 100, in spot mode. In center-weight averaging mode, however it is about one-stop over exposed (for high-key/brightly lit scenes, which are what were giving me problems). I suspect that I used center-weight averaging on the rolls of film that caused me problems.
Thanks again for the assistance.
