Per your quote....





"A question for the experienced, pro, or knowledgeable: what would be
the best way to learn the technical aspects of photography? What are
the rules of thumb that you use for specific instances? I plan on doing
landscape, city scape, candids, portraits, whatever, so don't hesitate.
Was there a particular source that you learned a lot from? A book,
magazine, video of some sort, or etc?"





A great book to start with,...."Understanding Exposure" by Bryan Peterson
