A 8 Hour Exposure of Stars creating Trails on Kodak Vericolor III ISO 160 Film. Using a Mamaya RZ 6X7 with a Super Wide Angle 50mm F4.5 ULD Lens. This shot was the second one I did. The first was a 6 hour exposure several years earlier at the same location. I waited for November, (long nights) a new moon, a remote location (no city lights or cars) high elevation, and just before snow closed the road. Thirty minutes after sunset with the camera set on Manuel I opened the shutter, set my alarm clock and went to sleep. Eight hours later I got up and closed the shutter. The commercial airline traffic pattern for Oakland and San Francisco is just south of Sonora pass so there were no jets passing through during the exposure.
