I got permission to get onto the roof of the Sirna facility in Boulder to take pictures. I had been planning to do a panorama for some time, and saw some colorful clouds developing. I got up to the roof in time and got the picture. I also noticed an interesting sign (someone working there apparently thought they were “God”). By the time that I got the images for the Boulder Flatirons panorama the colors were gone, and the light had gone flat.
While working part-time in Boulder, I was living a Marriott Residence Inn that was just a short distance away from the Sirna facilities. From my office, I noticed that it was getting dark out with some ominous clouds approaching. I took this sh0t while walking to the Residence Inn.
Star trails from my room at the Marriott Residence Inn in Boulder, Colorado. Composite of 180 images taken with a Nikon D3 camera and 24 mm f/3.5 PC-E lens (ISO 200, 24 mm, f/5.6, 30 sec exposures). Raw images processed with Capture One Pro 8, and combined using Photoshop CC 2014 (scripts, statistics, maximum). Note that these images were taken using the in-camera intervalometer and noise reduction so for every minute, only 30 seconds of exposure. I’ve learned how to do it better since then — using an external intervalometer and doing the noise reduction post processing.
