Came across this today, and thought some of ya'll might like the article. It's geared twards the motorcyclist, but does discus some important things such as the rule of thirds, back lighting, depth of field, angling shots, and motion along with some other things...
It's a remdial for the pro but great for the begginer or intermediate
