More fireflies than last night. It was a bit warmer out. The activity dropped off after 23:30 when the temperature went below 60°F. Composite of images taken with a Nikon D4 camera and 200 mm f/2 VR lens (ISO 800, 200 mm, f/8, 30 sec).

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.
