Hi. I realize this is a bit out of date, but thought I would add it to the "archive."
I'm taking the Recording Arts program at Los Medanos College, and one of the instructors/engineers/producers (with several Grammys under his belt) showed us this arrangement a few weeks ago. In addition to the mics in the photos, two mics were flown about 20' high toward the rear of the studio, one along each wall, pointed at the wall, to pick up ambient sound. Made for interesting mix possibilities.
He also handed out the diagram in the second attachment to illustrate the micing for Herbie Hancock's album, "The Piano". The mic underneath the piano would be out of phase with the others.
