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.

Firefly Trails – Summer Nights in New Jersey.

Between thunderstorms I have been experimenting on the best way to photograph fireflies. I set out three cameras to take a series of 30 second images. The images were then combined into a composite using the startrails.exe program. For these three composites I used relatively high ISO’s and narrow apertures to get a wider depth of field. C&C appreciated.

For those that read my photoblog, I would like to know if you want to see my Google+ posts. I currently have these added automatically as a test when I post an image to Google+. The titles do not have the date that I have been using for my regular photoblog posts. C&C appreciated.

The bad news that I heard today is that the Sirius/XM Book Radio channel is going away as of 15-July-2013. The Book channel is one of the only reasons I have kept up my subscription to Sirius/XM. I have the Book channel on 24/7 both at home and in my car. My long distance drives will not be the same when lost listening to a story.
