For instance, I dived in the technical basics of my old SLR with this book I found at my parent's house: Photography - the guide to technique by Andrew Hawkins, Dennis Avon .
This is probably an outdated and now useless guide, but answered me many questions I had when I started.
But, if pressed, I would suggest this book.
Most colleges have continuing education classes in photography. Stanford for example, I know does.
Obviously, photos I take on my own are loosened up but I lean towards realism. Not using a flash is a deliberate decision to preserve as much of the lighting in a dark scene, even at the risk of underexposure or excess ambient light from a slow shutter speed. Anyway, the book you recommend is not a bad one, but on a brief skim, it's more about the history and place of photography than snapshot technique. I don't disagree that that has worth, it's just not what I'm aiming for in my admittedly brief guide.
