There was NO WAY I was going to try and balance this many cubic yards
of interior with that one little splash of sunshine on the white
piano....so I upped the shutter speed so it wouldn't just be a white
blob over there, and then concentrated on the rest of the scene.
Had I really wanted to preserve detail on the piano, if I were a high-powered architectural photog with an assistant, I'd have positioned some black scrim outside that window to cut the sunlight by a few stops.
The rest of the scene is lit as follows:
SB80 just around the corner beyond the piano, diffuser cap & bounced off a little corner over there.
SB80 way back around the corner in the dining room, bounced out of the corner.
SB80 in the stairwell. This one took a few attempts, because the stairwell has big windows and so was pretty bright, but there was one very dark area so I had to figure out how to light up that area without overdo-ing it in the bright areas.
SB24 w/ radio trigger in the kitchen.
SB600 on stand behind the column at image center.
On-camera 430ex aimed up and behind me, bouncing off the corner behind my head.
