North Tower of the Golden Gate Bridge, San Francisco Bay, Morning

February 14, 2011 G Dan Mitchell Leave a comment

The north tower of the Golden Gate Bridge, with San Francisco Bay, the San Francisco Oakland Bay Bridge, a departing ship, and the East Bay hills beyond in morning fog and haze.

I’ve been working on the color version of this photograph, which proved to be a bit more tricky than I would have expected. My recollection of the light on this morning was that it was very bright – with the backlit haze/fog – and quite blue. But, as often happens, the coloration in the camera was dissonant with my memory, and I had to think a bit about where I wanted to go with the photography in post. In particular, the sky had an odd pink cast that can often become more obvious when using a long lens and only keeping a bit of the sky right above the horizon.

The background on this photograph (and several others in the same series) is that it was made on an early February morning shortly after sunrise from a point high in the Marin Headlands of the Golden Gate National Recreation Area. For the most part it was actually a brilliantly sunny and clear morning, but an inversion layer was creating a thin blanket of fog/haze that was almost too bright to look at and which muted the details of the landscape. (It was also tremendously windy – making it a challenge to shoot with a long lens!) After making a few initial exposures from a more obvious location – and one that was slightly out of the wind – I decided to wander a bit and look for juxtapositions of various landscape elements with the shape of the north tower of the bridge. After a short walk I found this spot where the tower was centered between the two towers of the more distant western span of the San Francisco Oakland Bay Bridge, and where the view included a bit of the San Francisco waterfront along the right margin and the fog-covered flatlands below the East Bay hills.

As I worked I noticed a freighter leaving the Port of Oakland beyond the further bridge. I’ve watched enough of these ships heading across the bay that I have a pretty good idea of the path they follow, and I knew that this one would cross beneath the Bay Bridge and then turn to cross the frame towards the left – so I waited for it to reach the position just barely to the left of the closer bridge tower before making this exposure.

North Tower of the Golden Gate Bridge, San Francisco Oakland Bay Bridge

February 13, 2011 G Dan Mitchell 3 Comments

Black and white photograph of the north tower of the Golden Gate Bridge silhouetted against San Francisco Bay morning haze and the San Francisco Oakland Bay Bridge.

A week ago I posted a few other photographs from this early morning winter visit to the upper reaches of the Marin Headlands, from which I photographed the bridges of the San Francisco Bay, backlit by early sun and partially obscured by a low layer of fog and haze. Since I am not fond of adding poetic (or pseudo-poetic) titles to my photographs, preferring to let them say whatever they have to say on their own, I have resisted the temptation to call this one “The Three Towers.” ;-)

The dark shape in the foreground that dominates the frame is, of course, the north tower of the Golden Gate Bridge. Shooting it in this light is trickier than it might seem like it should be. The light coming from beyond, reflected and amplified by water and haze, is very bright – almost hard to look at directly. So the west side of the bridge is deeply shadowed. I like the dark and stark shape of the tower here – as opposed to the more familiar photographs front or side lit by late afternoon or evening light – but the trick is to keep just a bit of detail in that nearly black tower.

The scene posed another technical issue, though it probably isn’t visible in this small version. As the sun comes up and heats the atmosphere, and as wind blows (and it was windy on this morning!) there is a lot of atmospheric turbulence. Normally you wouldn’t notice this at all, but when you shoot with a long lens and enlarge the image you quickly see that sharp edges and fine lines take on an almost “painterly” quality as the atmosphere shimmers, much in the manner of a mirage.

Cascade, Reflected Sunlight

February 12, 2011 G Dan Mitchell 4 Comments

Sunlight reflects on granite ledges next to cascades on Tenaya Creek.

In this iteration of the “blurry-fast-moving-water-in-Sierra-creek” photograph, I was looking to cram a variety of elements into the frame – as you can see, the entire photograph is not filled with water. There is a transition from white water with flashes of sunlit light at the tops of the waves, through the water with smaller areas of foam, to water reflecting the golden late afternoon light from a cliff face on the other side of the creek, to some bits of streamside granite slabs along the lower right edge of the frame. To me, these areas of shallow water and wet rock reflecting more distant light almost have a molten quality.

One of the trickiest things about this photograph for me was dealing with the strong contrast between very blue tones in the shaded parts of the water and the very warm tones of the reflections. As every photographer knows, the light in shade can be very blue, especially when the subject is supposed to be white and is lit almost entirely by the blue sky, as is the case in parts of the turbulent water. Adjustments are necessary in order to make it look realistic and conform with the colors that our eyes tell are are there. (Our vision system is remarkable… but it is not objectively accurate!) But adjustments to the blue water, if applied to the warm tones of the reflecting granite, can end up looking bizarre and overdone in the opposite direction!

Whitewater, Tenaya Creek

February 10, 2011 G Dan Mitchell 2 Comments

Turbulent whitewater flows through an area of steep granite along Tenaya Creek, Yosemite National Park.

You can, of course, find a place to shoot subjects like this one all over the Sierra and no doubt in many other places as well. This photograph was made during a period of relatively high water early in the season and in a spot where the water flowed over some rocks in shade. Sunlight on the other side of the stream reflected into the water and revealed highlights, especially the flying spray that I allowed to blur with a somewhat slow shutter speed.

The moving water in Sierra streams and rivers seems to be an almost irresistible subject for many photographers, and I confess that I count myself among them. In some ways it is almost too easy to make these photographs, and one basic requirement is a willingness to make quite a few exposures. The instantaneous motion of the water and the reflections of light simply cannot be controlled or predicted, so one almost has to make many, many exposures. Of course, there is a bit more to it than pointing the camera at water and then repeatedly pressing the shutter release. It is important to find some sort of compositional interest first – it could be where water flows around or over a rock, a place where the light catches the water, or possibly just the twisting forms of turbulent water. Light is extra important in these photographs I think – most often the colors come from a combination of the blue-green shades of water full of foam and from reflected light from things that are out of the frame. (In this photograph, the light mostly comes from sunlight reflected off of granite on the far side of the stream.) Shutter speed is an important consideration, as a short exposure will stop or nearly stop the water and freeze the motion, a somewhat longer exposure can hold some detail but still allow blur along the direction of the flow, and very long exposures can create a misty and diffuse effect.
