Gone to See Central America and the Panama Canal. Semester at Sea Spring 2011 Enrichment Voyage on the MV Explorer. Ultimate Travel Photography Workshop II with Michael Mariant. Day 4: At Sea.
Comparison of Digital Noise Reduction Programs. Pre-dawn view of the Moon, Venus (and Mercury) over the Pacific Ocean. Professor Ian Campbell had us look for the moon and several planets in close proximity. Here are a couple of images taken with a Nikon D3x and 85 mm f/1.4 lens (ISO 1600, 85 mm, f/1.4, 1/30 sec). I needed the high ISO to even get a 1/30 sec exposure since it was still dark and the ship was moving. For each image I processed with no digital noise reduction, then with either NIK Define 2.0 or Topaz DeNoise 5.0.

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 updating images in My Image of the Day Photoblog, and My eBird (with images of nearly 450 bird species). hope post COVID-19 to be a world traveler again. 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.
