David Mathre Photography

Welcome to my Images of the Day Photo blog. My goal is to post images from each day of the year going back to 2006 when I got my first DSLR camera. Images I post on Google+ are also forwarded to this Photo blog. I am a retired chemist that worked nearly thirty years in the Pharmaceutical industry. I took my first DSLR camera on a road trip across the United States, and became hooked, with my new passion becoming a photographer. I now spend all my time traveling and taking pictures. Since then I have visited over 50 countries, many on Semester at Sea voyages. My photographic interests include travel, the natural world, landscapes, and photographic techniques. I always want to learn something new and the only way to become better is to learn from mistakes.

Star Trails. Elderhostel “Southwest Photography” 2008 Workshop.

The following image is a composite of five 30 minute night sky exposures taken during a Elderhostel 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 tiff files) but works better than when I try to merge the images as layers in Photoshop.
