Since we moved, going from Northern NJ to Central NJ, I have to learn the specific names of some of my favorite subjects to photograph, Dragonflies & Damselflies. We are seeing quite a few different types here, we just have to learn the names. Also Males and Females are usually quite different in coloring & markings, so sometimes it is difficult.
We went to Plainsboro Preserve, a 1000 acre Audubon Nature Preserve, looking for Dragons & Damsels and we found quite a few. Most were sitting on the path, warming on the warm gravel & stones. Unfortunately that made for very busy backgrounds. The one below cooperated by sitting on a small branch, giving me a nicer background. I was using a 300mm f/4 lens and was shooting at f/4 to help keep the background softer looking. I sacrificed depth of field for a cleaner looking background. So I tried to shoot fairly straight in to my subject on the first. And a slight angle on the second.
