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.

Early Morning Double Rainbow in Patagonia. Comparison of HDR (High Dynamic Range) Processing Programs.

Digital camera sensors are not able to deal with the full dynamic range that the human eye can process. The same is true with computer monitors and printers. There are several commercial programs that will combine over and under exposed digital images to provide a composite digital image that tries to express the wider dynamic range of the eye. I continue to evaluate the commercial HDR programs. The following images are of a early morning double rainbow taken at Lago Grey in Torres del Paine National Park in Chile during my Photography Workshop in Patagonia with Thom Hogan (10-January-2011). The inital image is the original single exposure. This is followed by four HDR images processed with 1) Photoshop CS5 HDR Pro, 2) Photomatix Pro, 3) Nik HDR Pro, and 4) HDR Express Pro. Please reply with comments on which HDR image you like or don’t like.
