Backyard Springtime Nature in New Jersey

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.

My interests include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.
