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.

(1) Star, Jet, and Firefly Trails. Summer Night Sky in New Jersey. (2) Further attempts to record a DSLR video image of the moon

A composite of 897 images looking south taken after midnight. I used the Startrails program for creating the  composite.

Second day attempts for a DSLR video of the moon continued to be problematic. It appears that the camera is controlling the exposure and not allowing manual selection of appature, shutter speed, or ISO. The only way I could get an exposure that was not way over exposed was to add a TC-E III 20 teleconverter (effective 1000 mm).

To confirm that there was not a problem with the camera or lens I took this following single image of the waxing gibbous moon with the same setup (Nikon D3s and 500 mm f/4 VR lens + TC-E III 20 teleconverter (ISO 800, 1000 mm, f/8, 1/200 sec))
