Morning, San Francisco Bay

Morning fog covers Oakland and the East Bay Hills as hazy sun illuminates sailboats and ships on San Francisco Bay beyond the Golden Gate Bridge.

This photograph was made from high in the Marin Headlands, after hiking up to the hill above Battery 129 near the high point on Conzelman Road, the scenic route that climbs this ridge above the Golden Gate. I had earlier shot a similar scene from a spot just a bit lower, but by now the morning fog and haze was clearing enough to allow a bit more sun to light up the waters of the Bay and to reveal a subtle blue color. (Later the blue would be much deeper, and earlier it had been nearly gray.) This particular shade of blue is one of the things I liked about this scene on this particular day.

The hill at lower left is part of the Marin Headlands and drops from the road almost straight down to the water. The small bit of land intruding into the frame on the left just above the wake of a boat is Alcatraz Island. Beyond that is Treasure Island and its companion, Yerba Buena Island. The latter is crossed by the San Francisco Oakland Bay Bridge, leading to Oakland which is just barely visible under the fog over the East Bay hills. Near the upper right is a tiny bit of one of the piers along the San Francisco waterfront.

Alpenglow Clouds, Mount Conness

Clouds lit by alpenglow drift across the face of Mount Conness beyond the Tenaya Creek drainage, Yosemite National Park.

Earlier this week I posted another photograph of the same evening. This one was shot a bit earlier (believe it or not!) than the other photograph, as the intense and perhaps unexpected color display was just getting started. I’ll have more to write about the phenomenon in a future blog post that uses this evening as an example, but it almost seem like the sunset progressed backwards (oxymoron alert!) as it went on. It had begun with very boring and low contrast light, somewhat flattened by a haze that took on an increasingly ghastly blue-green hue as the light began to fade. Although the surroundings were spectacular on this opening day of Tioga Pass Road, the light and atmospheric conditions seemed to be conspiring to show them it their worst (literal and figurative) light.

But just at dusk a hint of pink appeared in some of the clouds ringing Mount Conness, the tall peak in the upper left. At first it was so faint that only those of us who were looking for it might have noticed, and we perhaps thought that we were simply trying to convince ourselves that something was going to happen. But the color increased, and as the more distant areas picked up better light, they shone through the foreground haze more clearly, and this haze faded in the same way that a scrim does in a theater when the front lights dim and the stage lights rise.

I find that this type of scene provides some of the most difficult technical and judgment challenges. So often the goal in an image, especially if it is going to be a print, is to try to get as much light into the scene as possible. A lot of the work in post-processing, at least for me, is done with the goal of trying to fill the image with light by means of various careful adjustments, often involving the use of masked curve layers. But here, the coloration depends upon not being overly bright – too much light either decreases the intensity of the pink and purple shadings or else sends them off into the land of the grotesque and gaudy. And the light in shadows – and there are a lot of shaded areas in this scene! – is very blue, much more so than the untrained eye would imagine when looking at the scene in person. This requires another set of tricky and subjective judgments – it would not look right to leave portions of the scene as blue “as they really were,” nor would it look right if the blue were diminished too much. But how much is right? There is no objective answer that I know of, so the goal (for example, on the large granite face of Polly Dome at the left) is to come up with a balance that seems blue enough but not too blue. A similar issue arises in these dark areas when it comes to deciding how bright is bright enough. Believe it or not, virtually nothing in this image is actually black, with the possible exception of a few very tiny areas in the lower left. The luminosity of the very dark areas had to be lifted a bit… but how much is just right? Again, a matter of personal judgment about which there is no objectively right answer.

All of that technical stuff aside, this evening provided one of the most glorious, albeit brief, displays of sublime light I have seen in the Sierra.

Young Trees and Meadow, Tioga Pass

Young Trees and Meadow, Tioga Pass

Young trees grow along the edge of subalpine meadows at Tioga Pass, Yosemite National Park.

This meadow, right below Tioga Pass – which is among the trees in the saddle in the upper part of the photograph – is something of a magical spot in the Sierra. It is, of course, the highest point that you can drive to in the park, and it sits right on top of the crest of the Sierra Nevada. At just slightly less than 10,000′ of elevation it is verging on the true alpine zone. Because of elevation and location, it is only open for a few months each year between roughly the end of spring and generally some time in November. (For those of us who think of this as it looks in summer, it is sobering to remember that during the majority of the year it is a cold and snow-covered place.) Once you pass over Tioga you begin to descend into the very different world of the high deserts east of the crest. Yes, it still feels like the high country for a while, but within miles you are in hot dry places that are not at all like this alpine terrain.

Oddly, while a thin band of trees crosses the saddle at the pass, much of the area on either side is meadow. This section is on the “Yosemite side,” and is an extension of the many meadows along the Dana Fork of the Tuolumne River which drains this area around Mount Dana. As if to reinforce the idea that this is not as gentle a place as it may appear in the summer, parts of the meadow are filled with the bleached remains of trees struck down by avalanches from the ridge that is out of this photograph to the left. The trail to the summit Mt. Dana, of the second-highest peak of Yosemite (being a few feet shorter than Mt. Lyell), begins by crossing this meadow.

Although I drive over this pass with some frequency, I virtually always stop and get out of the car and look around for at least a moment. On this late-July visit I stayed more than a moment, spending a good portion of an afternoon wandering about the meadow and photographing these young trees, small streams and ponds, fallen trees, some of the more distant mountains, and much else.

Big Sur Coastline Near Soberanes Creek, Spring

Big Sur Coastline Near Soberanes Creek, Spring. California Coast. May 13, 2011. © Copyright G Dan Mitchell – all rights reserved.

A sunny spring morning along the Big Sur Coast at Soberanes Creek, with fog above the coastal mountains.

This is a spot that is probably familiar to many who have driven down this section of the Big Sur coastline south of Monterey and Carmel, California. To the right, and out of the photograph, is Soberanes Canyon which ascends steeply toward the ridges above Pacific Ocean. A creek flows down the canyon, underneath the coast highway, and then into the ocean.

The foreground bluff looks inviting with its green color and spring flowers. However, I picked up one of the worst cases of poison oak I’ve had on one occasion when I walked across this meadow to photograph the sea stacks and coastline at dusk!
