One problem is that a lot of people are "taught" to pick up SLRs that have meters and simply line up the needle to the middle and away they go. That was my introduction to photography. Oh, and that 'A' was "Auto". FOOLS. It also took me many rolls of film and much frustration before I realized the difference between the matrix-metered N80 and the center-weighted Nikkormat and so on....

I've tried to set up auto modes on my camera before and just end up wasting film. There's nothing inherently difficult about setting a manual exposure, and with practice anyone could learn the nuances. But with practice I could also learn how to use Lightroom. But I won't.
