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.

Pink Flower — Macro and Wide Depth of Field. 

I used the pink flower from yesterday as an exercise to practice with a macro lens, flash, and Helicon Focus to get a macro image of a flower with an extreme depth of field in focus. Ten images of the flower were taken from rear focus to front focus by manually adjusting the focus distance on the lens. The raw images were processed with Capture One Pro, converted to 16 bit Tiff files, and then processed with Helicon Focus. Even though the lens was set at f/22, the actual focus plane was very narrow and thus needing several focus distances for Helicon Focus.
