I really enjoy night photographs. Once the sun goes down everything changes. The sunlight that normally illuminates a photograph is replaced by secondary lighting and that lighting can take unusual and dramatic forms.
Night HDR – March 31, 2012

These two photos are HDR (High Dynamic Range) combinations of 5 photographs, each photo one exposure value apart. Combining them in this manner allows a wider dynamic range (the variance of tones between pure black and pure white) than is normally available with a camera. The human eye has a wider dynamic range than a camera does and this method allows multiple photographs to be combined to provide more range than most cameras are capable of providing.

Tennessee Sunset – July 15, 2011
I was in Brentwood this evening and noticed the sun going down behind these hills. I found the contrast of the timeless hills and the more modern antenna structures, both silhouetted by the vivid colors of the setting sun, to be interesting. Since I had my camera it only seemed fitting to record it. |
Moon Phases – April 17, 2010
I’ve recently developed a moderate interest in astronomy. Unlike most of my hobbies I don’t expect this one to develop into a passion, but it is very interesting to look at the night sky through a telescope. One of my requirements was that whatever telescope I got had to have provisions for connecting my cameras, and these are my first attempts with that combination. The moon has been going from nothing to full the past few days (it is scheduled to be full on April 28) and I’ve been capturing photos of it through my telescope.
All photographs were taken with a Celestron SLT 1300 telescope using a 2x Barlow T-Adapter and a Nikon D-90. The T-Adapter takes the place of the lens on my camera so there is no aperture adjustment, all exposures are at f/5.0 with an effective focal length through the telescope and 2x Barlow of 1,300mm (or a 35mm focal length of 1,950mm).
To try and give some scale to the photograph, and the size of the craters that are visible, the diameter of the moon is 2,159 miles and the average distance from the earth is roughly 235,000 miles. Obviously some of the craters are enormous!

13% waxing crescent — April 17, 2010 — 1/125 second at ISO 1600
This was my very first attempt at photography through my telescope. I’m satisfied with the results but I think I can do better.

Nashville, TN – March 30, 2010

This photo of the moon was taken on March 30, 2010. It wasn’t “Colorized”. The moon was very low on the horizon when I took the photograph and the yellow tint comes from the light being diffused through the atmosphere. It was shot with a Nikon D90 and 300mm lens. 1/125 second @ f/8, ISO 200.

Nashville, TN – March 18, 2009
The two photographs below were taken on March 18, 2009 and are of traffic at the intersection below my home. The disembodied “Tubes” that lights make always intrigue me.
