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 Springtime Nature in New Jersey.

The Rhododendorn’s that the deer didn’t eat last winter are currently in bloom. The following five pictures are the same image processed differently. The first image is the straight out of the camera imbedded jpg image with no post processing. Next next four pictures were processed with Phase One Capture One Pro 6; Nikon Capture NX2; Adobe Lightroom 4; and Adobe Photoshop CS6.

I’m interested in comments which version you like or dislike.

Springtime Nature in New Jersey.

I stopped by the nearby Sourland Mountain Preserve on the way home from work to see what is new this spring. I was mainly looking for wildflowers and butterflies. One of the first things I found was hundreds, if not thousands of tadpoles at the edge of the pond. In a few weeks there are going to be a lot of frogs!
