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, Moon, Jet, and Firefly Trails. Summer Night Sky in New Jersey.

A composite of 980 images looking south taken before midnight. I used the Startrails program for creating the  composite.

I had actually gone out to see what type of a video I could take of the moon using the D3s camera and a telephoto lens. The moon phase (according to the US Naval Observatory site) is waxing gibbous (76% illuminated). I started by shooting some single images and found that ISO 200, 500 mm, f/8, 1/50 second should be about right. Even though I had the camera set to shoot in manual mode, all of the images of the moon were way over exposed. It didn’t appear that I had manual control while taking the video. I made sure that the ISO setting was fixed (not Auto), that Active D-Lighting was off, and that the white balance was fixed (4000 K). I need to try this again!
