Beeline Highway (AZ State Route 87) gets a lot of traffic at the end of the day each weekend, but it probably sees even more traffic on holiday weekends. Below is a photo that I took from a location near the Ballantine Trailhead on the Pine Creek Loop Trail.
The blue lights in the photo below were made by two police cars that drove by during the three minutes that the shutter was open. I’m guessing that the was an accident of some kind because shortly thereafter, the southbound lane (with the white lights) had no traffic for seven or eight minutes. Then, after that hiatus, there was even more traffic than before, probably due to the police lifting the roadblock.
I used the Zeiss 24mm lens on a NEX-7 for this shot. Exposure parameters are f/6.3, ISO 100, for 179 seconds. I used an IR remote to open and close the shutter in bulb mode. I did a short test shot at f/1.8 and used that to guess at the time needed to make a longer exposure at f/6.3.
