I am a scientist by training (Eckerd College, BSc; Caltech, Ph.D.). I worked for 27 years as a Chemist in the Pharmaceutical Industry developing processes to manufacture medicines for human and animal health. I now spend my time as a photographer and world traveler. My interests include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.

Backyard Summer Nature in New Jersey.

While sitting on my deck this evening, I captured images of some Grey Catbirds. Although the birds are pretty drab, they are good for practicing good long-lens technique. I used a Nikon D300 camera. The smaller DX sensor gives the illusion of 1.5x magnification for the 600 mm lens. I can get the same effect by using the D3x camera and cropping to the same size. Down side for the D300 camera is that the sensor is not as good in low light, and that the processing speed and buffer is not as fast as the D3 series camera bodies.

I also saw a Ruby Hummingbird, however it was too close to focus with the lens I was using. There is nothing much in bloom right now, so I might get a hummingbird feeder to see if I can get some local hummingbird images.

Backyard Summer Nature in New Jersey.

As this doe was eating clover, she was being eaten by a swarm of flies. She didn’t have her fawn along this evening.

Backyard Summer Nature in New Jersey.

Another composite image of fireflies in my backyard. This time with a telephoto lens at f/13 to try to get a deeper depth of field effect. As before, the  camera was set up to take 25 second images, and the resultant 110 images combined using the Startrails program.

Backyard Early Summer Nature in New Jersey. Moth or Butterfly?

I saw this insect while sitting out on the deck this evening. It landed at just beyond the minimum focus distance of the lens. Two images with slightly different depth of field (f/4, 1/125 sec) and (f/5.6, 1/60 sec). Both shot “mirror up” with 30 sec delay to allow the lens to stabilize.
