The media tends to distort facts and blow events out of proportion. Perhaps you’ve noticed. The latest example is this week’s “supermoon,” an event heralded on TV, in print, and online like the Second Coming. Okay, now for a little perspective. Despite hype to the contrary, a supermoon occurs at least twice, and up to five times, in a year. In fact, our last supermoon was all the way back in October, and the next one isn’t until December.
But, as I’m sure you’ve heard, this month’s supermoon was special, an event the likes of which we haven’t seen since 1946, and won’t see again until 2034. True enough. But exactly how special was it? Not nearly as special as you might have heard: the diameter of the “epic” November supermoon was only one-half of one percent (.57) larger than the October full moon, and four-fifths of one percent (.84) larger than the December full moon—differences that are impossible to discern with the naked eye. Next year we’ll get two moons that are more than 99 percent the size of this month’s supermoon, and last year we had four.
So why was I out taking pictures of the full moon Sunday night? Because I think every full moon is beautiful, regardless of its size, and I take any opportunity to photograph it over my favorite landscapes. Which is also why each fall I schedule a workshop in Yosemite to coincide with the full moon.
Thursday night my Yosemite Autumn Moon workshop group photographed an 82% (of full) waxing gibbous (on its way to full) moon above Valley View at sunset. For Friday night’s sunset, from a quiet beach beside the Merced River we glimpsed through clouds an 87% moon rising just right of Half Dome. Saturday’s sunset found us beneath a magenta sky at Tunnel View to witness the 96% moon ascend between Sentinel Dome and Cathedral Rocks.
The workshop’s grand finale came Sunday night, when we gathered at the Half Dome vista on Big Oak Flat Road. Though I rarely encounter other photographers for any of my moon rise/set shoots, limited parking and tripod space here prompted me to arrive an hour before sunset. That turned out to be a fortunate decision, as within 30 minutes of our arrival the parking lot was brimming beyond full and photographers swarmed the nearby rocks like ants at a picnic.
With an hour to kill, I made sure everyone in my group was ready (but by now, this being our fourth moonrise, they were experienced veterans) and chatted with other photographers nearby. Comparing notes, it seemed that most (all?) of the other photographers had relied on apps like The Photographer’s Ephemeris and Photo Pills to plot the moon’s arrival location and time, while I was the only one clinging to my old fashioned topo map, scientific calculator, trigonometry plotting approach. (I do it this way because I’ve been plotting the moon since long before the apps were available, I feel like I can be more precise, and I enjoy it—not necessarily in that order.)
In the viewfinder of my Sony a7R Mark II, atop my tripod and armed with my Tamron 150-600 lens to enlarge the moon as much as possible, was the composition I wanted—assuming the accuracy of my calculations. The consensus among others seemed to be that the moon would appear from behind Half Dome’s right flank, anytime between 5:00 and 5:10 p.m. I stuck to my guns that the moon would show up at about 5:05, and that it would be straight over the top of Half Dome. While I saw this more as an opportunity to check my plotting method’s accuracy than a competition between methods, it was pretty thrilling when the moon popped into view right on schedule and on target. Take that, technology!
Since the moon didn’t appear until a full fifteen minutes after sunset, the extreme dynamic range (very dark landscape beneath a daylight-bright moon) made this an extremely tricky exposure for anyone (like me) not interested in compositing two images (one with the moon properly exposed, another with the scene properly exposed). To capture this scene with a single click, I closely monitored the pre-capture “zebra stripes” highlight alert in my a7RII and pushed my exposure 2/3 stop after the first hint of the alert appeared. To hedge my bets and give myself processing options, I varied my exposure 1/3 to 2/3 of a stop in either direction (an exception to my standard workflow because the moon is too small to register on the histogram).
The result was a scene that looked quite dark on my LCD, and a moon with no detail. No problem, I reassured myself, for my a7RII’s ridiculous dynamic range. This morning in Lightroom I adjusted the white balance, pulled up the shadows, and pulled down the highlights. In Photoshop I applied a moderate dose of Topaz DeNoise and did a few minor dodge/burn moves to get the image you see here.
One more thing
The size of the moon in this image has virtually nothing to do with the fact that this was a “supermoon,” and virtually everything to do with the fact that I was far enough away to be able to use a 600mm lens. Click below to read about how to capture your own big moon:
