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.

Time-lapsed Night Sky Video and Star Trails.

Wide-angle night sky time-lapsed video looking south in New Jersey (~600 1 minute images taken with a Nikon D3x and 14-24 mm f/2.8 lens at 15 mm and f/5.6). The moon was from another night (video taken with a Nikon D3s and 600 mm f/4 telephoto lens). The overall video sequence created using Adobe Premiere Pro.

The images were also combined in groups of 100 using the Star Trails program to create the following south view star trails. The orange background is due to clouds being lit from the towns to the south. In the last two images the moon is visible.
