I killed two birds with one stone the other evening: I did some “blue hour” photography, and I made some panorama images. I have been wanting, for some time now, to get out and photograph the “blue hour”. For those of you who are unfamiliar with the term, it refers to the hour before sun-up or after sundown when the light from the setting sun is reflected in the upper atmosphere. The more common name for this time is twilight, and it is divided into three distinct phases: civil, nautical, and astronomical. The duration of twilight changes depending on the time of year, and the latitude from which it is being observed. The blue reference has to do with the color of the light which has a wonderful bluish cast to it and is diffuse without any harsh shadows. So, I finally made myself go out into the diminishing day and drive to the Rio Puerco Valley. The prospect was sweetened by the full moon which would be rising about half an hour after sunset.
I arrived at my destination two hours before moonrise and set about scouting the area for a good location to photograph the event. Since I am quite familiar with the place, it didn’t take me very long to find what I was looking for. I set up my camera on a tripod and began making test images to determine the correct exposure. As the sun went down and the light softened, I began taking several series of vertical photographs which would later be stitched together in Photoshop to create the final panorama. The first image was made about thirty minutes after sunset and about twenty minutes before moonrise.
The second photograph was actually made earlier than the first, but it was more of a test to get the feel for shooting the panorama and I didn’t expect to take it any further. After all, it’s full of cattle, which I consider to be a blight on the landscape. But, in the spirit of expanding my horizons (thank you Robin), I processed the image and, as it turned out, I liked it.
From the information I had gathered from The Photographer’s Ephemeris, I expected the full moon to rise somewhere between Cabezon Peak (the volcanic plug in the distance) and Cerro Cuate (the more prominent double peaked mount). But as the horizon began to brighten I was somewhat dismayed to discover that the moon was not where it was supposed to be…well at least not where I expected it to be. I checked the app on my iPhone again and saw that my expectations were based on a location that was actually a couple miles east of where I was.
I had planned to include the moon with the two mountains in the composition; that wasn’t possible from the place where I was standing. Now I had to re-think my plans, knowing that my window of opportunity was small if I was going to capture the moon close to the horizon. I quickly packed everything into my car and drove to the new location, walked to a place which afforded a clear view of the scene, set up, and composed the last image. By now it was dark, I was shooting thirty second exposures, and I was having to focus manually–auto focus doesn’t work very well in the dark. This being my first attempt at photographing at this time of day, and making panoramas, I wasn’t really very hopeful about the outcome. As full dark descended, I pack up my gear by the light of my headlamp and headed home.
The next morning I set about uploading and processing my previous night’s work. Each panorama is composed of nine vertical images which are then stitched together in Photoshop. As the first panorama was rendered I knew I was hooked. Somehow, despite the comedy of errors I had experienced while making the images, I managed to walk away with some finished photographs that I was happy with. It’s always an exhilarating feeling to discover a new technique and this was no exception. I made a few mistakes; there are some things I will do differently in the future, but overall, I’m happy with the way things turned out. It was a good night’s work.
