The Mist Trail at Night

Claudia and I made a nighttime trip up the Mist Trail recently. The ostensible purpose of this hike was to look for lunar rainbows, and we did find some, as you can see from the photos. But that was just a bonus. The real reward was being up there on a beautiful, moonlit night, with the roar of the falling water filling our ears, and having this normally-crowded trail completely to ourselves. It was so much fun.

The moon will be full on Thursday night, and with the good water flow this spring I expect that many photographers will be making their way to Yosemite to photograph lunar rainbows on Yosemite Falls. Don Olson has posted lunar rainbow predictions for Lower Yosemite Fall, but the spray will be soaking the bridge below the lower fall, making it hard to keep lenses dry during long exposures. Unfortunately Don hasn’t posted any predictions yet for Upper Yosemite Fall, and my trigonometry skills aren’t good enough to make those predictions myself. I think lunar rainbows will be visible on the upper fall from Cook’s Meadow at some point on Thursday evening, and the following couple of nights, but I can’t be positive!

First Signs of Dogwoods

Dogwood blossoms, Yosemite Valley, from April 21st, 2007



Last year the dogwoods in Yosemite Valley bloomed two or three weeks sooner than normal. This year they seem to be on a more typical timetable, but may still arrive a bit early.

Claudia and I were in Yosemite Valley on Tuesday afternoon, and saw the first signs of the dogwoods blooming. When dogwood blossoms first appear they’re small and green. Over the course of about a week or so they gradually become larger and brighter until they turn completely white. (Except for the centers, which become yellow-green. Those centers are the real flowers; the white “petals” are actually bracts.) On Tuesday there were lots of green blossoms, and only a few white ones. We didn’t see a single tree with all-white blossoms, only a few that were partially white. But that should change pretty quickly. There should be a few trees with all-white blossoms by this weekend, and I’d guess that the majority will be in full bloom by the end of next week.

Focus-Stacking Season

Poppies, lupines, goldfields, and tri-colored gilia, Merced River Canyon, Wednesday afternoon. A focus-stacked blend of four different frames.

It’s spring, which means it’s wildflower season, and focus-stacking season.

There’s been a secondary poppy bloom in the eastern end of the Merced River Canyon near El Portal. No big swaths of poppies, but smaller patches, and some of those patches are mixed with other flowers, which always makes things more interesting. Claudia and I spent the afternoon up there on Wednesday, and had a great time. I’ve included a couple of my favorite images from that day here.

As I was processing the images later, it occurred to me that all of them required focus stacking. Literally every single one. And this is very common for me when photographing wildflowers. I don’t need focus stacking often in other seasons, but in spring I use this technique all the time. It’s just difficult to get everything in focus with one frame when photographing wildflowers. I’m frequently picking out a particularly dense patch of flowers, and using a telephoto lens to emphasize patterns and visually compress the space, making the flowers look closer together. Even with careful focusing and f/22 it’s impossible to get everything in focus with a long lens raking across a field of flowers like that. But even with wide-angle lenses it’s sometimes difficult to get everything in focus with one frame, because I’m getting really close to the foreground flowers, so there’s a tremendous amount of depth.

Another View of Yosemite Falls

Rainbow, mist, and Yosemite Falls, Yosemite NP, CA, USA

Rainbow, mist, and Yosemite Falls, March 14th

I recently wrote about photographing a clearing storm from the Four-Mile Trail, but that was actually my second journey up that trail last month. The first time was a week earlier, on March 14th, as another rainstorm cleared early in the morning. At that time I hadn’t been up the Four-Mile Trail in several years, but I remembered that you could see some great views of Yosemite Falls from the trail, and the unusually high early-spring water levels in falls made it seem worth trying.

I had a vague memory of finding some good views of the falls that weren’t very far up the trail, but apparently my memory was faulty, as all the lower views were partially obscured by trees. I found a decent view about 600 feet above the valley floor, but kept going up and up the switchbacks until I reached some better spots. On the way I also saw misty scenes looking west toward Cathedral Rocks and El Capitan, which I had to photograph, giving me a convenient excuse to stop and rest:

Redbuds and Poppies

Redbuds in the Sierra Nevada foothills, Mariposa Country, CA, USA

Redbuds in the Merced River Canyon, Monday afternoon

The redbuds have been coming along nicely in the Merced River Canyon, along Highway 140 west of Yosemite. I drove through the canyon on Monday, and most of the redbuds were blooming. Not all of those that were blooming were fully open yet, and some redbuds were still just budding. On the other hand, I saw a few that were starting to leaf out. Overall I’d say they were not quite at peak, but there were plenty of beautiful redbuds to photograph. They’ll probably peak around this weekend, or next week.

It was harder to tell what was going on with the poppies in the canyon. In late February it was starting to look like we would have a great year for poppies. There were a couple of very colorful hillsides in the western part of the canyon, and the bloom was spreading further east. But since then we’ve had a lot of rain. While rain is usually good for wildflowers, poppies like warm sunshine — at least once they begin blooming. A stretch of cold, rainy weather will cause already-blooming poppies to pack it in for the year and go to seed.

Staying Flexible on a Snowy, Misty Morning

Sun breaking through fog in an oak grove, Yosemite, 8:06 a.m. yesterday

Friday’s storm got cold enough to drop a couple of inches of snow on Yosemite Valley. The storm cleared during the night, but showers lingered until the wee hours Saturday morning. It seemed possible that we might find some mist at sunrise, so Claudia and I drove up early to Yosemite Valley.

Indeed there was some mist, and broken clouds overhead. That seemed like a perfect combination for Tunnel View; if the clouds lit up it would be a gorgeous sunrise from there. But soon after I arrived at Tunnel View the clouds dissipated. There was still some mist down in the valley below, but it would take awhile for the sun to get high enough to light that mist, and without clouds to block it the sun would be right in my face, making it difficult to avoid lens flare.
