Three-Years Ago (25-February-2008) — Colorado

Elderhostel “Photography in the Southwest” Workshop Day 1. Star Trails.

The following image is a composite of five 30 minute night sky exposures taken during a Elderhostel/Road Scholar photography workshop at Kelly Place outside of Cortez, Colorado in 2008. It was really dark other than the Christmas lights at the main building, and you could see a lot of stars in the sky. I moved the tripod as far away from the lights as possible and decided to do this series with a fisheye lens that would give a 180° field of view. The five images were combined using Startrails. This program is old (only works with jpg or 8-bit tif files) but works better than when I try to merge the images as layers in Photoshop.

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.
