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.

Two-Years Ago (07-September-2009) — Alaska

Gone to See North America Road Trip. Day 17: Denali National Park, Alaska. (Day 3: Nikonians ANPAT 9).

View of Mount Denali on a clear day from the Stony Hill Overlook (mile 62). This is on the only road into Denali National Park. Private vehicles are restricted to the first 15 miles into the park. To go beyond that point you either need to walk or take the (hop-on, hop-off) buses provided by the National Park Service.

Two-Years Ago (06-September-2009) — Alaska

Gone to See North America Road Trip – Nikonians ANPAT 9. Day 16: Alaska Railroad – Anchorage to Denali National Park, Alaska.

Two years ago today ANPAT 9 had just started. I took this image of Albert while we were on the Alaska Railroad traveling from Anchorage to Denali National Park. I am working on a time-lapse video using the images I took on the train trip.

Backyard Summertime Nature in New Jersey.

This tree fungus was not staying still long enough to keep in focus. I used a feature in Capture One Pro where I selected a color, and then reduced the saturation for the inverse colors (thus B&W + one color). We will see if the Blob is blocking my driveway tomorrow morning.

Five-Years Ago (05-September-2006) — Washington

Gone to See America 2006 Driving Tour. Day 11: North Cascade National Park, Lake Chelan, Washington.

Five years ago I took the Lady of the Lake ferry from Chelan to Stehekin and back. It was about two weeks since I purchased a Nikon D200 camera. This was my first DSLR, and I barely knew how to use it. I took this image of a female mallard with a 80-400 mm VR lens. I really liked the look, and it became one of the reasons that I have been spending much of my time learning how to be a better photographer. There are three images, the original and two crops. My sister also made a print of this image that I have in my dining room.

Family Portrait Session

I need to redo this with Helicon Focus so I have greater depth of field and the trolls are in focus.
