Tioga Lake, Late Spring

February 22, 2011 G Dan Mitchell 3 Comments

Late spring at icebound Tioga Lake below Tioga Pass with Mammoth Peak and the Kuna Crest beyond in afternoon light.

I made and shared a slightly different photograph of this scene last summer, but when I did my annual end-of-year traverse of the year’s raw files I returned to the original set of images and wondered how I missed this one. In a lot of ways it is similar to the one I selected earlier, though the foreground light and shadow patterns are a bit different and, more importantly, I like the position of the clouds in this one more than what I had in the original. So, there are now two versions of this scene floating around…

After several fairly dry years in California, the winter of 2009-10 produced much more precipitation, as rain in the lowlands and as snowpack in the Sierra. Because of the heavier snow, Tioga Pass opened just a bit later than average, and when it opened there was still a lot of snow in the high country. Since this afforded a rare chance to cross the Yosemite Sierra in conditions not usually seen by drivers I made it a point to get up there as soon as the road opened.

On the drive there was snow along almost the entire length of Tioga Pass Road, and in many places it looked more like winter than like spring. At the same time, it was spring, and the melting of the snowpack was fully underway. While lakes like Tioga Lake, as seen in this photograph, were still ice-covered… the ice was thinning quickly, and everywhere the melting snow was creating creeks and cascades. The high country, especially at the elevation of the road, was filling with water – water in ponds, water in overflowing lakes, water in rivers, water in cascades and waterfalls. I was waterfalls along the road in places where I had not even suspected that there were creeks!

This photograph shows Tioga Lake, just east of and below Tioga Pass, the eastern entrance to Yosemite. The pass itself is in the low saddle just above the meadow ascending the hill at the end of the lake. Beyond, and inside the park, is massive Kuna Crest with white, snow-capped Mammoth Peak in full sun at the right end of the ridge.

Turnstile Shadows

February 17, 2011 G Dan Mitchell 1 Comment

Shadows cast by sodium vapor lamps shining on old turnstiles at Mare Island Naval Ship Yard.

This old row of abandoned turnstiles stands at the entrance to an alley through which we almost always walk as we begin shooting in the core area of the historic Mare Island Naval Ship Yard near Vallejo, California. It seems odd to see the structure here since now one can just walk around them, but I suspect that this area must have been somewhat secure at times since military ships were built here.

This isn’t an easy subject to photograph. Several of us were talking about how we have struggled to find a composition built around the turnstiles. I have one other photograph that I made a few years ago that I think works pretty well. In that one I aimed a bit higher and let the metal structure pretty much fill the frame, and I also ended up making it a black and white image. (It was used as a cover for a book at one point.) But on this evening a few of us were staring at the turnstiles again and remarking that there must be more photographs in there… somewhere… but that we are still trying to find them.

I thought it might be interesting to make the long and complex patterns of the shadows fill most of the frame, so I moved back just a little and pointed the camera down so that just a portion of the turnstile structure appears at the top of the frame. This also helps with a couple of technical challenges: the bright lights beyond the structure create a tremendously large dynamic range in the scene, and it can be difficult to keep some distracting background elements (like a stop sign!) out of the image. The garish yellow/orange light is from a large sodium vapor lamp that sits above the intersection on the road in the background. That coloration is part of what made me choose to make the previous photograph of this subject black and white, but on this night I decided to go with the color.

The final image is a blend of two exposures. The shorter one was selected to avoid blowing out the brightest areas in the upper part of the frame, and the longer one let me keep a bit more detail in the shadowed asphalt foreground.

Lamp, the ‘UFO Building” at Night

February 16, 2011 G Dan Mitchell Leave a comment

A lamp casts a shadow in bright artificial light in a night photograph of the wall of the ‘UFO Building’ at Mare Island Naval Shipyard.

The first time I photographed the side of this weathered and peeling building and Mare Island Naval Ship Yard, I didn’t see the feature that gives this building its informal name. I’ll be that you can though, right? Due to a lucky alignment of this small exterior lamp (which appears to be non-functional) and some nearby sodium vapor lamps, the lamp casts a shadow on the corrugated wall of the building that has a striking and easily recognized shape!

It may not immediately be apparent that this photograph was made at night in very low light. However, a look at the lighting should make it apparent that this cannot be daytime light. Note that the lamp that creates a shadow to its right… is also getting some nice illumination from the right side! One of the fun things about shooting in an industrial location like Mare Island is the amazing mixture of lighting sources. Though it wasn’t much of an influence on this night, the full moon can provide light that is color balanced pretty much like daylight… only a lot dimmer. The sodium vapor lamps that light this area (they are common in street lamps) produce a strongly yellow or yellow/red light. Occasional fluorescent or tungsten lamps provide yet more color variations. In the end, it is just about impossible to say what kind of color balance is “real” – and doubly-so since the actual shooting conditions are near darkness. The only reason that images like this look daylight-bright is because they are typically the result of long exposures. In fact, this one was relatively short at just over a minute. Somewhere in the 2 to 5 minute range is perhaps more typical.

The crazy lighting is apparent in this image if you look a bit more closely. As mentioned above, there is cross lighting here from both sides of the frame. While the strongest light comes from the left (and creates that UFO shadow) there is also significant light from a bit further away to the right. You may also be able to see that the in some areas the shadows created by light from one side are filled in by garishly colored lights coming from the other directions – see some of the very yellow areas along the sides of vertical boards and along the ridges of the corrugated wall.

Conway Summit Aspens, Autumn

October 14, 2010 G Dan Mitchell 3 Comments

Layers of colorful autumn aspen groves lead up toward Dunderberg Meadow and Peak above Conway Summit, California.

I often plan my visits to this large aspen grove on the high point of highway 395 just north of Lee Vining for late afternoon, when the rows upon rows of large aspen groves are back-lit by the afternoon sun as it drops towards the crest of the Sierra Nevada near Dunderberg peak. Each grove tends to change color at a slightly different time, and each can take on a different shade ranging from green (in the case of those that change a bit later) to golden and red and orange. This year, in this area, the colors seem to tend more towards gold/yellow and less towards red/orange, but no matte what the shade they light up in this light.

I was extra lucky on this afternoon in that there were clouds. Talk to many Sierra photographers about the weather and you’ll discover that we are not so fond of the “perfect blue sky weather” that so many others love. Yes, it is “pleasant.” No, it is not necessarily visually interesting. It had been that sort of “perfect” weather for the first couple days of this visit to the “east side,” but in the middle of the afternoon on this day puffy clouds began to form over the crest, and their shadows added texture and brought out the shapes of hills and ridges beyond the aspens.
