I don't wanna understand! Just give me the friggin formula to the perfect exposure! And I need a condensed version of that Tutorial thread. Too much information.
J/K.
I learned with the instructions on the Kodak box. Then I got a 35mm slr with a meter that worked, but never gave the correct answer. Compensated using a Lunasix handmeter. Exposed thousands of feet of Tri-X, Extachrome, etc. mostly correctly for the subject at hand.
Now I have a consumer-level DSLR and... a good in-camera meter, and lots of dial options. The choice of tools to use depends on the situation.
Static light, relatively even tonality, OCF, macro: Manual.
High variability, but DOF control important: Aperture priority.
High variability, but shutter-speed control important, Shutter priority.
In the end, it's about using the right tool to get to the result you want in the most efficient (quick) way possible.
