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.

Autumn in Pennsylvania: New Mirrorless Camera (Nikon 1 V1).

I got up early this morning to see how the new Nikon 1 V1 mirrorless digital camera performs. I spent the night reading the manual to get an idea of how to use the camera. As with anything new, you have to use it to really understand its capabilities. I drove to the Lambertville – New Hope bridge for some early dawn images. The Delaware river was up a little over 4 feet in the last day due to all of the rain we got on Tuesday and Wednesday. Still below flood stage but up more than usual. The following image is an old building in New Hope along the Delaware river, taken from across the river in the Lambertville Station parking lot. The Raw image was converted to jpg using Adobe Lightroom 3.6 RC with no additional processing. Note that I had to upgrade from Lightroom 3.5 to the 3.6 Release Candidate in order to be able to see and process the image with Lightroom. More images to follow, and I need to check out if my other Raw image processing programs are able to handle images from this new camera.

Later in the afternoon, I had a great Thanksgiving dinner with neighbors across the street. (Images next post). Right now the camera is outside to see how it performs capturing Night Sky images.

New Mirrorless Camera: Nikon 1 V1

It is 4 years ago today that I got my Nikon D300 while returning from a photography workshop with Thom Hogan in Hawaii (23-November-2007). Coincidentally, I received the new Nikon 1 V1 today from B&H. I was surprised that it was heavier than my Leica X1, but a lot lighter and smaller than a Nikon D700 or D3. Lots to learn. I like the Leica X1 because it has dials on the top for both aperture and shutter speed (designed for a photographer). These are missing on the Nikon V1 (have to use buttons/dials on the back). I got all four available Nikon 1 lenses 10 mm (27 mm equiv), 10-30 mm (27-81 mm equiv), 30-110 mm (81-297 mm equiv), and 10-100 mm (27-270 mm equiv). The 10-100 mm (VR) lens is larger and heavier than the camera for this evaluation. The Nikon V1 does have an electronic view finder (100%). Missing is the adapter for Nikon F-mount lenses (which I really want so I can have a mirrorless camera on my Questar telescopes). Reading the manual there seems to be some interesting video options. Lots to learn over the next 4 days.

Four-Years Ago (22-November-2007) — Hawaii

Gone to See Hawaii. Big Island Photography Workshop with Thom Hogan. Day 5: Volcano National Park.

Four years ago I attended a photography workshop on the Big Island of Hawaii led by Thom Hogan . We spent Thanksgiving day in and around Volcanoes National Park. Later in the afternoon we had a wonderful Thanksgiving dinner at the Volcano House Hotel with other guests at the Lodge and some local residents.

The day started shooting sunrise over the Kilauea crater. In order to record the wide range of light, I took seven images with different exposure times. These were then processed using Photomatix (a HDR program). While traveling to the next photography location, Thom and Tony spotted a Nene (the Hawaiian state bird, also known as the Hawaiian Goose). The Nene is probably distantly related to Canada geese, however the Nene do not migrate. I guess that once they found Hawaii, they decided to stay 🙂 . The Nene almost went extinct and is now protected by the state. It can also be found on some of the other Hawaiian islands. Finally, Thom helped with a composition including a fern.

Gone to See Hawaii. Big Island Photography Workshop with Thom Hogan. Day 4: Kona and Volcano National Park.

Four years ago I was attending a photography workshop on the Big Island of Hawaii led by Thom Hogan . Before breakfast, I wandered down to the harbor and captured a Hawaiian Outrigger Canoe with a Cruse Ship in the background. We spent a good part of the day driving to Volcanoes National Park. We stayed at the Lodge — Volcano House Hotel within the National Park through Thanksgiving. After getting settled, the group went for a hike down into the rain forest from the lodge where I took these three images. The first is a wild yellow orchid along the trail, the next a purple fungus (?) on the forest floor, and the third a palm frond. All three of the images used my SB-800 flash, where Thom was helping me learn how to best compose and use fill-flash to light up the subject of the image. Although we didn’t experience much rain, a few days after we left the park got 13 and 17 inches of rain and we would have been spending our time taking images of the fireplace (which has been burning continuously since 1877). The Volcano House Hotel is now closed. Unfortunately, the fire went out on 01-January-2010. The hotel is now being renovated, and will not open until sometime in 2012.

Gone to See Hawaii. Big Island Photography Workshop with Thom Hogan. Day 3: Beach at Waipi’o Valley.

Three images taken four years ago while I attended a photography workshop on the Big Island of Hawaii led by Thom Hogan . The first image is two women running to the ocean at the beach at Waipi’o Valley. The second image is of a palm tree overlooking Waipi’o valley, located along the Hamakua Coast on the Big Island of Hawaii. The third image is a sunset over the ocean (location unknown).

One thing that Thom helped me with during the workshop was how to compose an image with at wide-angle lens. You can see an example at Waipi’o Valley beach with subjects near, mid, and far distance at the following link: 20-November-2007. The other lesson was to include a human subject to give perspective and scale to the overall image. The image at the link above includes Thom as the mid distance subject.
