San Francisco Bay morning fog over begins to break up over Alcatraz and Yerba Buena Islands and the San Francisco Oakland Bay Bridge.

I made this photograph back around the start of spring in 2009. I recall shooting from the Marin Headlands back toward the Bay as the fog began to break up, still obscuring the view but allowing beams of light to begin to come through the gloom and light up portions of the Bay. Alcatraz Island is at upper left and beyond that is the Treasure Island and Yerba Buena Island complex.

Many things intrigued me about this scene. Although it is in shadow still, Alcatraz stands out as the clearest object in the scene. The patterns on the water were amazing, created by a combination of the normal surface waves, the wakes of ships that had passed, and the mottled and mixed lighting of areas of fog and sun. Beyond the main subjects and over the East Bay shoreline around Oakland, light beams come down from the clearing fog.

This photograph is also an example of why I save and later review all of my raw files. Either because I don’t understand the image when I first make it or perhaps I move on to the next project too quickly sometimes it is not unusual when a photograph “slips through the cracks” and I end up overlooking it. This was one of those photographs… which I now find hard to understand.

Two Oaks, Morning Sun

The springtime morning sun shines through a pair of oak trees in the Calero Hills south of San Jose, California.

On the final day of April and for the first time this season, I found to go for a hike at my favorite local park, a place where I have walked just about every available trail (and invented a few routes of my own) and photographed for a number of years. The park would not seem like anything all that special by comparison to some of the other places I visit, but it is close and I’ve gotten to know it in a way that makes it more special. The place is called the Calero County Park, part of the Santa Clara County Parks system.

The entrance to the park is in a broad valley that is largely occupied by stables. (Or, used to be – it looks like the stables must have closed since last season.) Rising from this valley are the typical grass-covered hills of central and northern California, with oaks and other trees scattered around and, in places, thicker trees and brush. At this time of year, the hills turn what I call “impossibly green” – and if you have seen them on a late-winter or early spring morning you know what I mean.

I started this hike a bit after dawn, so the golden hour light was more or less gone. I had a general idea of photographing some wildflowers (which didn’t happen – it was too windy) and some oak trees that grow alone or in small groups on the grass-covered hills. I passed a small lake – where a single egret often hangs out, but not on this morning – and topped a rise and descended into a small valley from which I have made quite a few photographs of oaks. It didn’t look too promising at first, but at the far end of this area I noticed that a pair of trees were still obscuring the sun and that I might be able to shoot straight into the sun with the trees blocking its disk, and get a photograph including the tree shadows on the hillside grasses.

This turned out to be another of those all-too-common ephemeral photographs in that the sun was starting to rise above the top branches of the tree and would soon be “out in the open,” making it much too bright for what I had in mind. So I worked quickly to set up tripod and camera and select a lens, then frame a composition, focus, and make a series of exposures that might be needed to deal with the huge dynamic range between direct sun and backlit tree trunks. By the time I had everything set up and was ready to shoot the sun had already risen above the upper branches, so I ended up looking for a slightly better shadow and putting the tripod down very low – and this gave me must enough time to make the series of exposures I figured I would need.

In the end, I got lucky. One single shot somehow managed to not blow the sun out too badly yet hold enough detail in the grass that a bit of work in post could bring it back. With all of the potential for lens flare – which I had to some extent in every shot – this one only had two small bits of it, and they were easily dealt with.

Beams of light from brilliantly lit clouds send beams of light past downtown San Francisco buildings and toward the waterfront.

Anyone who knows San Francisco might be wondering about this light – and I wouldn’t blame them. These were really unusual conditions. Believe it or not, the photograph was made very early in the morning, perhaps a bit less than a half hour after sunrise. Which begs a couple of questions: why is the light coming from the right (west to southwest) at dawn? And, why does the light seem to be coming from such a high angle?

The light beams are not direct sunlight. The sun is actually far to the left of the frame and very low in the sky. Its direct light was blocked by intervening fog clouds. As the clouds moved from left to right, thinner areas in the cloud cover were struck from behind by the very low angle sunlight coming from the left and set aglow. It was the brilliant light from these areas of backlit clouds that cast the light through the mist and between buildings. What you cannot see in the still photograph is that as the clouds moved the beams of light slowly swept from right to left. From moment to moment the light beams would angle from right to left, then straight down, and then left to right.

Another amazing thing was that I appeared to be the only person out making photographs of this…

Early mornng sun breaks through clouds over San Francisco Bay and illuminates the water to silhouette Alcatraz Island.

This weekend I visited Muir Woods again. I was on the road early enough to arrive at the north end of the Golden Gate Bridge by dawn. Even if I am headed somewhere else, I almost always stop at the north end to see what sort of light is shining on the City and the bay – and this morning low clouds from an incoming weather system were sweeping across the bay as sunlight broke through intermittently to light the water on the bay. Before heading on to Muir Woods I made a series of photographs of this light, including this one of Alcatraz.
