Since this is especially true of production sound, I decided to make it my main focus, along with articles about post written with the student, audio newbie or indie filmmaker in mind.
Another sound blog, Film Sound Daily! (which I've mentioned before) covers the "big boy" movies, and has incredible access to folks who normally aren't addressed in the traditional coverage. In their most recent post, they talk to recordist Rob Nokes about field recording for post during production.
Anytime a movie has a unique situation involving crowds or machines it makes sense to capture the original on location as the costs to re-stage unique events are usually cost prohibitive.
