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.

Late Summertime Nature in New Jersey.

I went out for a walk this morning in the local Sourland Mountain Preserve. I was stalking a small Green Heron trying to get some images of it catching a fish or frog. All of a sudden there was a commotion in the middle of the pond. Two Canada Geese started a full out smackdown. It was like a junior high school fight. The other geese in the pond formed a circle and made noises supporting their team. The small Green Heron didn’t know what to think.

I used the images taken with a Nikon N1 V2 camera, FT1 adapter, and 180 mm f/2.8D lens to create a short time-lapse video.

Backyard Late Summer Nighttime Sky Over New Jersey.

Last night the sky was clear, and the waxing gibbous moon (61%) bright, so I set up a couple of cameras with big lenses out on the deck. One of the systems (Nikon D4 camera TC-E III 20 teleconverter and 600 mm f/4 VR lens (ISO 400, 1200 mm, f/8, 1/60 sec)) was set to record video (1080p, 30 fps). While reviewing the videos I noticed one with something (a bird?) passing in front of the moon. Played back at 10 fps shows the transit to occur over 25 frames.
