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.


One-Year Ago Today — New Jersey

Autumn Night Star and Jet Trails in New Jersey. Composite of 118 images taken with a Nikon D810A camera and a 24 mm f/3.5 PC-E lens (ISO 200, 24 mm, f/5.6, 120 sec). Raw images processed with Capture One Pro, and Photoshop CC. The composite was created using Photoshop CC Scripts/Statistics/Maximum. In the past I would have done this with startrails.exe, but now can do it directly within Photoshop CC with the RAW or TIF images, and not have to convert the images to JPG first. I kept the camera pointed low enough so the moon did not get into the image. The new at the time D810A camera with battery pack lasted for 223 two minute images (7 hours 25 minutes). The temperature got down to freezing, but the lens did not cloud over with dew or frost. The other neat thing about the D810A camera is that you can program exposures up to 900 sec in the camera without needing to use a MC-35 intervalometer. With previous Nikon cameras you were limited to 30 sec exposures.
