A 6 Hour Exposure of the Stars creating Trails on Kodak Vericolor III ISO 160 Film. I used a Mamaya RZ 6X7 with a Super Wide Angle 50mm F4.5 ULD Lens. This time exposure was the first one I took. The second was a 8 hour exposure several years later 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. Six hours later I got up and closed the shutter and went back to sleep. The commercial airline traffic pattern for Oakland and San Francisco is just south of Sonora pass so there are no jets passing through during the exposure.
