"...your question about ISO settings on the Vivitar flash was pretty
good."
It was _bad_ question, because it showed that the questioner didn't
understand one of the simplest and most basic principles of photography
-- the relationship between exposure and film speed. The math is trivial
-- simple multiplication or division.
You may forget the facts, but if you know the _principles_, you'll
always be able to figure things out.
"To the snobs who have figured it all out, photography is essentially a
lot of complex math that we thrive on. If you doubt that, then please
try explaining the Zone-System to me."
Okay. The Zone System is _very_ simple. It's based on two principles:
1. You can calibrate exposure and development to produce consistent
results.
2. Once everything is calibrated, you can relate exposure of a specific
brightness level in the scene to the production of a specific gray tone
on the printing paper.
These principles make it much easier to "previsualize" the results
you'll get when you print the negative.
