Moving Rock, Overcast Morning Sky – Racetrack Playa

April 4, 2010 G Dan Mitchell 4 Comments

A “moving rock” beneath overcast morning skies at the Racetrack Playa, Death Valley.

First a bit of background about “the Racetrack,” the location of the famous “moving rocks” in Death Valley National Park. About 25 miles out in the desert back-country of the park on a very bad gravel road there is an isolated and desolate playa known as “the Racetrack.” (For those considering a visit, getting to the Racetrack is no trivial matter. The drive takes nearly two hours one-way and the road is awful, with some of the worst wash-board surface I’ve ever encountered. There are absolutely no services along the road or at the Racetrack – no water is available and your cell phone won’t work.) The name of the place comes, in some circuitous way, from the mysterious rocks that have clearly traveled across the playa, sometimes many hundreds of yards, and left tracks gouged into the playa surface. The most likely explanation for the phenomenon involves a combination of a periodically flooded playa, extremely high winds, and rare occasions when it is cold enough to freeze the surface of collected water, locking the rocks in place and allowing the wind to move them. I’ve never heard anything concrete about the frequency of this alignment of conditions, but as far as I know no one has ever observed the rocks actually moving, nor is there any indication that they have moved recently.

I’ve been out there three times in the past, and had great conditions for doing photography. On this visit I had plans to photograph in sunset and sunrise light and to attempt night photography of the rocks under the full moon. (I did the latter once before, but was less familiar than I am now with how to best do this with a DSLR.) Since I’ve had such good luck with weather and lighting conditions in the past, I suppose I was due for less than optimum conditions… and that is what I encountered. Shortly after arriving at the playa the sky was covered by high, thin clouds. Except for a brief moment close to sunset this made late day photography difficult. The overcast stuck around until I left then next morning, making the planned full moon night photography an impossibility, and the morning light was also challenging.

That said, I’m still glad I went. Standing in the middle of this empty playa completely alone as the day ends or begins is an amazing experience that few people get to have. And I did manage to bring back a few photographs that I think will “work.” This one was shot fairly early in the morning at what might have been around sunrise, if a sunrise had actually occurred.

Rock Patterns, Mosaic Canyon

April 3, 2010 G Dan Mitchell 6 Comments

Folded and twisted rock forms in Mosaic Canyon, Death Valley National Park, California.

Although this formation is found very near the entrance to the canyon, on this visit I also managed to wander further up the canyon than I have in the past, discovering very different and far more open terrain that what I had seen before. Mosaic Canyon, a short drive up the hill from Stovepipe Wells, is known for its very narrow and twisty lower section, its access to higher regions of the Mount Tucki area, and the striking and unusual rock formations laid bare by erosion from water traveling down the canyon in past floods.

In the lower canyon there is a section where this beautifully banded rock runs alongside the trail. Sometimes that patterns are a bit hard to see, but this time it appeared that recent rains and the soft afternoon shaded light brought them out a bit more. This section featured ribbon-like folds in the surface of the rock that must have been created by water erosion.

Powerplant, Railroad Avenue – Mare Island Naval Shipyard

March 7, 2010 G Dan Mitchell 2 Comments

Night panoramic photograph of the powerplant building and other structures along Railroad Avenue at the historic Mare Island Naval Shipyard, Vallejo, California.

This is a bit of a first for me – a night photography stitched panorama. This image is composed of two separate exposures which were aligned and “stitched” into a single image in post. (As such, it could be a very large print!) Shooting from an elevated position, I shot almost directly north (as you can tell from the star trails in the larger version). The view looks up Railroad Avenue past the iconic power plant building with its smokestack that is visible from all over Mare Island.

I’m usually a bit casual about exposure time with long exposure night photographs. It isn’t that I don’t care – it is just that one has a ton of leeway when it comes to the very long exposures I typically use. For example, on a 3 minute exposure you would have to be off by three minutes to overexpose by one stop! So rather than use a stopwatch or an automatic timer I just count to myself. I’m usually will within a 10% error, and that is good enough. However, when stitching “good enough” often isn’t. The separate component frames really need to be quite similar, so in this case I resorted to using my watch to get relatively accurate 90 second exposures.

Another interesting factor in night photography is illustrated in this photo, namely the wildly varied colors of the light sources we deal with. There are three dominant sources in this image. The overall illumination comes from the full moon, which is quite similar to day light in terms of white balance. On the near wall of the brick power plant there is very “hot” and saturated yellow/red tinted light, probably from sodium vapor lamps. Near the left end of the image is an old wooden building that is illuminated by very green light, which I believe comes from mercury vapor lamps. I often chuckle a bit when people speak of “white balancing” the color in a scene like this. If you pick one source for your white balance you’ll throw the others even more out of line. My philosophy is usually to just go with what looks right!

Finally, the idea of making the stitched panorama came from the recently started Panocturnists web site, begun by people connected with The Nocturnes, the San Francisco Bay Area night photography group. I was intrigued by the idea of creating panoramic night photography, and I’ve done a few images along these lines on my two most recent visits to Mare Island.

Towers and Brick Building, Full Moon Light

March 6, 2010 G Dan Mitchell Leave a comment

Industrial towers and brick building under the light of the full moon at Mare Island Naval Shipyard, Vallejo, California.

On February 27, for the second time this month, I visited Mare Island Naval Shipyard to do night photography with The Nocturnes, the San Francisco Bay Area night photography group. (Anyone looking for great resources on night photography should visit their web site. They also offer classes and workshops on night photography.) This was a “Mare Islands Alumni” event, attended by quite a few folks who have done night photography at Mare Island. One of the highlights came before the actual photography began as we met in the museum building and had a chance to view work by participating photographers – the work gets better every time and there was some wonderful night photography on display.

One attraction on this night was the full moon, which appears just above and to the right of the frame in this photograph made near the intersection of 8th and Nimitz Streets, in the heart of the old ship construction area. The was the first subject I photographed – it was something of a “do over,” since I had overlooked some obvious composition problems with the shot earlier this month and wanted to get it right this time. When I originally mentioned that, Tim Baskerville pointed out that I might have a hard time getting the same reflective puddles in the scene, but as luck would have it a good sized storm was just departing and it left great puddles everywhere!
