Three trees obviously. Pine, Maple, and Birch. Two at Rachel Carson National Wildlife Refuge and one just down the road at Laudholm Farms. I don’t know if you can call it a “good” use of an ultra wide frame of view, but I like to try it on occasion. 🙂 Sony a5100 in-camera HDR at 18mm equivalent. Processed in Polarr and assembled in FrameMagic. The trick of course is to be really close to the tree…but then trees are not that shy.
