Yesterday was the first day of summer, and my backyard is full of firelies. I set up a camera to take 25 second images, and then used the Startrails program to combine ~150 image (ISO 400) for the first image and then ~100 images (ISO 6400) for the second image. The D3s can see in the dark, and I didn’t take it all the way up to 100K ISO.

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 in photography include the natural world, wildlife, landscapes, skyscapes, and seascapes. I have traveled to over 50 countries over the last 10 years, often on Semester at Sea voyages. While at home in New Jersey, I spend time on a home renovation project and expanding my wildflower garden/meadow.
