Ansel Adams: Frozen Lake and Cliffs, Sierra Nevada, Sequoia National Park, 1932

Recip failure during long exposures can do all kinds of weird things with contrast, depending on the specific film and filter involved. That becomes quite apparent when learning to make color separation negatives...

True, but that has little or no negative consequences for me and most landscape photographers...just another tool we can use.

And I agree -- people create little boxes to put things too easily.
