After Before Friday Forum Week 15

My submission to Stacy Fisher’s After-Before Friday Forum for Week 15 was taken at the Bodie State Historical Park in California earlier this month.  Bodie is a kind of preserved ghost town and, thanks to the leader of a photo workshop, our group of about ten photographers had the town to ourselves.  Gold was discovered here in 1859, but not much happened until the mid-1870s when a rich vein of ore was discovered. By 1879, the town was booming and population surged to some 7,000 people.  But a decline soon followed as better mining prospects were discovered elsewhere. By 1910, less than 700 people lived there and eventually the town was abandoned.

Today only 5% of the original buildings remain, but they all are fascinating as photographic subjects.  As the sun was setting, I started looking for a building that had windows facing to the west so I could catch the reflected colors of the sky and clouds and also include a good part of the sky in the overall picture.  The sky was much brighter than the building, so checking the histogram was critical in making sure that some detail would be present in the shadows of the building and the sky would not be blown out.  (Technical Info: Nikon D800E on tripod with 14-24 mm lens extended to 14mm; exposure 1/15th sec. @ f/16, ISO 400).  The aperture setting was to insure that both the building and the sky would be sharp.  In order to include more of the building on the left and sky on the right, two images were taken to capture the entire scene.  The final image would be a Photomerge of  the two images.  But the processing was the same for both in Adobe Camera Raw (ACR).  But to keep things simple, the initial “Before” image shown below is just one of the two shots.  This initial image shows the original file without any changes made in ACR.

As it turns out, almost all of the processing was accomplished with the tools in ACR.   The Screen Capture below shows the ACR dialog box with the changes that were made.  The red arrows identify the sliders and the adjustments were as follows:

Highlights: decreased to -21 (to tone down the bright spots in the sky and the windows)

Shadows: Increase to +48 (to open up the dark tones on the building and in terrain)

Whites: Increase to +25 (to set the white point)

Blacks: Decrease to -6 (to set the black point)

Clarity: Increase to +28 (within my usual range of 25-30)

Vibrance: Increase to +28 (to bump up the colors in the sky just a bit and add warmth to the building)

 Adobe Camera Raw Adjustments

 The two images, both with these settings, were then opened in Photoshop and combined into a single panorama format using the Photomerge tool.  The merged result is shown in the image below.

After Camera Raw and Photomerge

The final step was to darken the sky just a bit more. Using the Polygon Lasso Tool, (feather = 20 pixels) the sky was selected and then a Curves adjustment layer (blend mode = normal) was applied to recreate the colors that I saw that night.  The image below shows the Photoshop display after this step had been implemented.  The first five steps in the History panel (red bracket) show the steps of the Photomerge.  The remaining steps show the selection of the sky and the application of the Curves adjustment.

Final Photoshop Adjustments

That was it for the Photoshop segment.  I tried a few other adjustments, such as darkening the reflection of the sky in the windows and also adding a touch of saturation to the overall image but none seemed to improve the scene, so it ended with just the one small tweak.  The difference is small and may be difficult to see in this smaller size, but the final result is shown below.

Final Image

Thanks again to Stacy Fischer for organizing and maintaining this forum. You can see the other contributions at her site later this morning.  You will find some excellent examples of how others bring the image as they envisioned it into reality.


Shooting theStars at Gaylor Lake

When conditions are perfect, the Gaylor Lakes area of Yosemite National Park can be a wonderful location for photographing star trails and the Milky Way. There are some drawbacks, however, not the least of which is a hike of about one mile starting at about 10,000 feet and going up about 600 feet before descending 250 feet to the shore of Middle Gaylor Lake.   The second aspect that might give one pause is that the hike back is in near-total darkness.

Undeterred, our group started out about two hours before sunset and before long we reached a saddle ridge overlooking Middle Gaylor Lake—a classic alpine lake nestled in a broad basin—a sparkling blue oval below us. The scenery in all directions was spectacular, a sufficient reward by itself for the effort we had expended.

But we were here for the stars that would appear in a few hours and so we started scouting possible locations. As we did so, two hawks circled overhead and an occasional marmot gave us disapproving stares. But no other human was here, another payoff for the hike we had just completed.

My goal was to make a second attempt for the so-called ecliptic, the location in the sky where the field of stars appearing to rotate counter-clockwise around the north star borders the stars appearing to rotate clockwise around the southern hemisphere. I had come close at Mono Lake, but tonight I hoped for a more obvious display of the divergent lines.

If there had been no wind, the lake would have served as a mirror for the scene in the sky, but this was not in the cards for last night. But complaints were muted because near-perfection is not a bad deal when you think about it.

Thanks to Michael, our workshop leader, I was lined up nicely as the image below demonstrates. This image is in fact a composite of 20 exposures, each 4 minutes long taken in quick succession.

After about two hours of photographing star trails, the group gathered at the northern end of the lake to take advantage of the Milky Way’s location, hovering over the “infinity pool” edge of the shoreline.   Our hopes for an end to the windy conditions continued to be disappointed, so there would be no mirror effects tonight. The image below is one of several taken, with the golden light of Fresno outlining the horizon to the south.

Star Trails

Last night featured an attempt to produce a star trails image, a long time exposure that tracks the movement of the stars in the sky. The members of the workshop group assembled in various locations along the shore of Lake Mono and waited for nightfall. There are two basic ways to create such an image. The traditional procedure is to leave the shutter open for a long time, say about 90 minutes) and take just one image. A second method is to take a series of shorter images, say about 4 minutes long, and combine them in Photoshop to produce a single image that seems to have an unbroken set of star trails. The benefit of this latter approach is that it produces images with less noise or digital artifacts. More on this in a future post, but I decided on the multiple image approach.

When shooting a star trails sequence, one has to decide where to point the camera. If it is pointed directly at the North Star, the trails of the other stars will appear as concentric rings around the center point. If you point somewhat away from the North Star, the effect is different, depending on the direction of the camera. Last night, I chose a northeasterly direction. The rocks in the water were illuminated during one of the exposures and some unintended ambient light caused the dim illumination of the foreground rocks during another exposure.

A fair amount of minor adjustment work (removing jet trails, etc.,) is necessary after the images are downloaded, but those actions have been postponed until I get home to a better display monitor than I have with me here. What is shown below is the preliminary result, which provides a pretty close idea of what the final image will look like.

The Milky Way

The night sky, unsullied by the artificial lights of civilization, never ceases to amaze me. Even here in Yosemite National Park, you cannot find absolute darkness but you can get pretty close. Last night was the first night of our night photography workshop, led by Michael Frye, and Olmstead Point in the eastern portion of the park would be ground zero.

We arrived about an hour before sunset and hiked a short distance up an inclined granite dome littered with glacial erratics and a scattering of pine trees that somehow had found places to grow on this massive stone. This little jaunt took us only about 100 yards from the parking area, a spot that provides a premium viewpoint for little effort. This will not be the case two nights from now, however.

But I digress. If you are in a good location, capturing a single image of the Milky Way is relatively simple, except for one minor thing: focusing in the dark. It doesn’t work to simply turn the lens to the infinity point until it stops because modern lenses are designed to go a little past infinity. We were given several techniques to try (subject for a future post) and I opted for using the Live View function on my camera.

The Milky Way becomes visible to the naked eye about 2 hours after sunset and then moves slowly across the sky as the earth rotates. This gives one the opportunity to find several possible compositions using foreground objects and/or the horizon.   The highlight here would come at about 11:00 PM when the Milky Way would be directly above Half Dome, seeming to erupt from this iconic feature of the park in a spectacular arc across the entire sky above us and disappearing into the horizon to our north.

In order to capture as much of the sky as possible, we all used very wide-angle lenses and in my case, that is a 14-24mm f/2.8 zoom. The image showing Half Dome is below. Because it is several miles away and the lens was set to 14mm, Half Dome is a little hard to pick out in this small size, but it is there (the small bump in the valley on the horizon) if you look carefully.

The group then spent some time working on light painting, which involves using a flashlight or other light source to illuminate an object in the foreground while using the sky as a dramatic background. Michael knows Yosemite extremely well and he led us to a Western Juniper pine tree that he had found several years ago. The group clustered around the tree, each one selecting a different composition and on the count of three, shutters were opened and a member of Michael’s team “painted” the tree with a flashlight for about 2 seconds. The result is shown below.

Tonight, depending on weather conditions, the group will be off to another location. Again, thanks to Latte Da Coffee in Lee Vining for making this post possible with their wi-fi service. And another good cup of coffee which I desperately needed.


Tenaya Lake

Yesterday, I took advantage of some free time to do a little exploring along Tioga Road in Yosemite National Park. I found a nice view on the shore of Tenaya Lake. and returned about 90 minutes before sunset to see what would happen. It didn’t look promising with a relatively heavy cloud cover blocking the sun but it was a beautiful setting and there was a nice flat boulder to sit on while I waited.   Sure enough, the sun started breaking through about 25 minutes before the sun dropped below the ridgeline. The image below shows the result.

I should add my thanks to LAtteDa Coffee in Lee Vining for their wi-fi service. And a good cup of coffee as well.

Mono Lake

I’m back on the road again, this time in Lee Vining, California where I will be joining a night photography workshop led by Michael Frye. The class starts tomorrow, but that shouldn’t be reason not to go out at sunrise, especially when the body clock is on Eastern Time and something like Mono Lake is a short distance away. The one downside of this area is Internet poverty. So this will have to be a small post so it can fit through the little bitty Wi-Fi pipes that are available.

Summer Specials

Kenilworth Aquatic Gardens in Washington, DC is famed for its lotus display that peaks in late July.  This year I found time for only one brief visit about five weeks ago.  But I did manage to capture a few images which are shown below.  The most recent report I have on the status of the blooms is pretty dated–July 31st.  They apparently were looking very good on that day.  If you are thinking of going there now, it would be best to check ahead.  Here is the link the the Kenilwoth Aquatic Gardens website.  The best time to go is early morning.

Both images were taken with a Nikon D800E on a tripod, 70-200mm lens with an exposure of 1/640th sec. @ ISO 400.  The apertures varied only slightly, about f/4 ,and the lens was close to fully extended.

If all goes well next week, I should have an image or two from Yosemite National Park.  If Mother Nature is kind to me, I’ll have some images quite different from these.
