Blast from the past! That post was from '07
Prior to the real estate collapse I kept pretty busy in my spare time shooting virtual tours. I used a Nikon D70s, Nikkor 10.5mm Fisheye Lens, 360Precision Pano Head and a Manfrotto Tripod/Leveling Base.
Shot around at 4 different exposures and used stitching software by Kekus Digital called PTBatch to put it all together. In Photoshop I would start with the best overall exposure then lay it on top of one that was good for the windows. I would then mask around the windows and erase the bright layer to reveal the darker. It was a process of compromise and very rarely was I completely happy with the result. Except when I got paid. Which came to an end pretty abruptly in '08 when the entire economy tanked as a result of the gold rush in real estate.
