After seeing the images captured by the people in my group followed me on Monday evening, during the next day’s image review session a few in my workshop group asked if we could go back up to Glacier Point for sunset that night. I did a quick-and-dirty plotting and showed them about where the moon would be at sunset (I usually tend to be more OCD about precision when plotting the moon, but “about” was good enough for our purposes), explaining that I’d planned to photograph the moonrise from a different spot that night, but I’d be willing to forego that shoot in favor of a Glacier Point reprise if that’s what everyone preferred. But, I warned, tonight would also be our only opportunity to photograph the Lower Yosemite Fall moonbow—if we drive up to Glacier Point, we probably won’t make it back down to the valley for the moonbow shoot until after 9:00. While that would be plenty early enough for the moonbow, it would mean we’d have been going from before 6:00 a.m. until about 11:00 p.m. But the vote was unanimous, so back up we went.
I love plotting a moonrise. I’ve been doing it for a long time—when done right there’s no mystery to the time and location of the moon’s arrival, but there’s just something thrilling about the watching the moon peek above the horizon. (Not to mention the (unjustified) awe my workshop groups express when it happens exactly when and where I’d predicted.) When we considering altering the schedule I’d them that we’d see the at around 7:40, give or take five minutes, just a little to the left of Mt. Starr King. And sure enough, at 7:36 there it was, a white wafer poking from behind the left flank of Gray Peak (the left-most peak in the above image).
Before you decide that my moon prediction makes me some kind of photography savant, I should probably explain why the camera I used to photograph this scene was my backup, 1DS Mark III, and not my primary, 5D Mark III. (The 1DS III is still a great camera, it’s just seven-year old technology.) That would be because, genius that I am, my camera bag, complete with camera, lenses, tripod, and filters was still back at the hotel. Fortunately, knowing the way workshops force me out of my routine (leading to a long history of forgotten tripods and cameras abandoned by the roadside), I always have a backup tripod and camera bag with my backup camera and a lens or two in the back of my car. Which is how my 1DS III and 100-400 lens (which I find too bulky and awkward for everyday use) were back there and ready for action. What I didn’t have was my remote release and graduated neutral density filters, essential to my twilight moonrise workflow. Fortunately, one of the workshop students took pity on me and loaned me a GND she wouldn’t be using (thanks, Lynda!); I turned on the 2-second timer to eliminate shutter-press vibrations.
As cool as the moon’s appearance was, the best full moonrise photography doesn’t come until a little later. From about five minutes before sunset, when the sky has darkened enough for the daylight-bright moon stand out, until about ten minutes after sunrise, when the foreground has darkened too much to be captured with a single frame (even with the use of a GND), is my moonrise “prime time.”
But even though the best stuff wouldn’t come until later, I photographed the moonrise from its first appearance, varying my composition as much as the 100-400 lens would allow—getting Half Dome in the frame was out of the question, but since I’d already covered that the night before, this was going to be more of a telephoto shoot anyway. Everything was at infinity, but in this case I opted for f8 (f11 is my usual “default” f-stop) and ISO 400 because, given the weight of the 1DSIII and 100-400 lens, I was a little concerned about my tripod’s ability to dampen completely after 2-seconds. By the time the light got really good and the sky started to pink-up, I was quite familiar with all the compositions and was able to cycle through them very efficiently.
By about 8:15 we were hustling back down the mountain to our date with the moonbow. But that’s a story for a different day….
