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.

Fireflies in My Backyard.

Yesterday was the first day of summer, and my backyard is full of firelies. I set up a camera to take 25 second images, and then used the Startrails program to combine ~150 image (ISO 400) for the first image and then ~100 images (ISO 6400) for the second image. The D3s can see in the dark, and I didn’t take it all the way up to 100K ISO.
