Photographing the October 23rd. Partial Solar Eclipse

Sun and Moon chasing at Walker Lake, Nevada

Photographing the solar eclipse is one of my most stressful events because it does not occur very often and also due to the safety factors involved with protecting the eyes. Magnifying the sun through a lens without proper caution can cause permanent eye damage so I use a Baadar Astrosolar Safety Film that has been attached to a light-proof box that is mounted on the hood of my Nikon 500mm 4.0 lens.

The safety film is made by the Baader Planetarium in Germany and reduces intensity of sunlight by over 99.999%.

Just before 2:00 PDT when the Moon's silhouette was just starting to reach the top of the Sun's disk I was set up and ready to begin the photo shoot. As luck would have it, there were clouds but they were very thin and the sun was shining bright, and there was no wind to cause camera shake.

Around 2:19pm, the moon was just beginning to take a bite out of the Sun's disk. After a few trial exposures with the ISO at 200, the aperture at f/22, I selected a shutter speed of 1/2000 a second. After checking the image, I found that I had to adjust the camera settings to compensate for the dark filter.

At 2:26pm with camera settings readjusted to f/14, shutter speed--1/400 seconds, the sun appeared through the Baadar film in almost its actual color, neutral white, but with a slight bluish tinge.

Clouds move across Sun at 2:28pm and I adjust my settings for the reduced light to f/8 and shutter speed at 1/160 a second.

The Sun is nearing mid-eclipse at 3:14pm and time for more camera adjustments, I increased the ISO to 400 at f/5.6 with 1/640 a second shutter speed.

At 3:42pm the Moon's silhouette is almost half way across the Sun's surface and with less light coming from the Sun, I opened the aperture to f/4 and lowered the shutter speed to 1/80 a second.

After this time, the sun had dropped low in the west sky almost behind the mountains and the clouds were thicker. It turned out to be a nice day for catching the partial solar eclipse and the thin clouds added to the ambiance.

While processing the photos in Lightroom, I took the artistic creativity to add some color and enlarge the AR 2192 sunspot that has been so much in the news media lately.

And I must confess that I just can not help being a little creative with the enhancing tool just to see what colors appear.

What an exciting and interesting photo-adventure this day has been. I love it when I am drawn to an area and not knowing what to expect I get treated to new experiences.

Photography places me in the moment where I can share that moment in time. It becomes a life story as represented by my interaction with the scene. The happiness and beauty or the sorrow and strife; how I focus leaves a lasting impression that might touch the viewer on a spiritual level.

Composition and Technique in the Photograph

Getting it Right

I saw a post on Facebook from an aspiring photographer that went something like this: "I don't need to get it right with the camera, I'd rather spend time in Photoshop". At the same time, I am reminded of a quote from professional photographer Andrew S. Gibson, "A good photo is comprised of one-third the composition, one-third the lighting and one-third the technical ability of the photographer." I do agree with Gibson, and I had rather spend time in getting the photo, which I find both relaxing and exhilarating than sitting at the computer working out the tedious details.

Please don't get me wrong, I do enjoy the post-processing and love to play with my images in Photoshop or Lightroom. However, when I was learning the basics of photography, it was demanded that you get it right before the shutter was pressed. Furthermore, in the darkroom days before the enlightened digital era there was only so much that could be done with a negative compared to today's Photoshop.

Going back to the comment on not getting it right, I am reminded of several occasions where I was trying to get a particular photograph and had only that one chance to get the scene as it appeared in nature.

"The Challenge" has become one of my best selling photographs. I was tracking the sorrel stallion with my manual focus Nikon 500mm 4.0 lens as he was walking away after drinking from a pond. Suddenly the black stallion came out from the bushes, they reared up and it was over so fast that I hardly had time to focus. Since I wanted to have the natural terrain as sharp as possible in the photo, I pre-selected an aperture of f/8, which also gave me a faster shutter speed to catch the action.

The waterfall at Lost Creek Canyon only flows during times of adequate rainfall or snowmelt. One January, a winter storm brought heavy snow to Red Rock Canyon. Over night, the storm passed through and I was heading out early the next morning for photos. I saw the waterfall flowing from a distance and knew that I had to get these rare photos. After reaching the pool at the base of the waterfall, I selected my widest lens--a Nikon 24mm 2.8, and dropped my tripod all the way down in the water, as low as it would go. I chose an aperture of f/22 to slow the water, and then bracketed the exposure. My goal was to keep the detail in the features of the canyon without burning out the highlights on the top portion. No sooner than I had gotten off several exposures, the canyon began to fill with other people crowding in to enjoy the scenery.

"Summer Storm" has become another of my most popular images. Back in my film days, I had been waiting to catch lightning striking over the Spring Mountains near Las Vegas, Nevada. Early one evening, I watched the clouds build and began to notice streaks of lightning. After driving into the desert over a dirt road to get closer to the action, I used my Nikon 80-200mm 2.8 lens to focus on the area where the lightning was really striking. With camera secured to tripod, I held the shutter open with a cable release for two minute intervals at f/ 5.6. I was allowed four exposures before the wind and rain forced me to pack up and leave.

On June 5, 2012, Venus made a historical transit across our Sun. This was one event that I really wanted to photograph, so I did my research on solar photography and hoped for a clear day with no cloud cover. To photograph the sun, I made a lightproof box with a Baader solar filter and attached it to my Nikon 500mm lens with a 2X teleconverter. I selected an aperture of f/4 and bracketed the shutter speed from 1/125 seconds.

I guess it’s an ego thing because I love being out getting the photos, but I also love the thrill of seeing the scene as it appeared in nature load in on my computer monitor. If I choose to alter the photo, I can always go back to my original which was shot as close to natural as possible.
