On our photo walk at Davidsons Mill Pond Park, I noticed this Immature Common Whitetail male dragonfly warming on a rock. It had a cluttered background behind the dragonfly, so I shot 3 images wide open, f5.6, at different focus points. 1st on the left wing, 2nd on the body, then the right wing. When I was working on the files, I loaded the 3 images in one layered Photoshop file. I selected all three layers and selected Auto-align, then auto-blend for the final merged image. When you do auto-blend Photoshop automatically blends what it thinks are the best areas to use for the final blended image. Sometimes you might need to do a tiny touch up here or there, but usually it does a pretty good job. Since I was using a tripod for these images they lined up nicely and I did not need much in the way of touch-ups on this image. I was using a 300mm f/4 with a 1.4x teleconverter. To keep the background smoother I was shooting wide open, but with a 1.4x teleconverter that would be @ f/5.6. Usually when I use a teleconverter, if there is enough light, I stop down a little more then I usually do to help with sharpness. On a 1.4x I stop down at least 1 f/stop, on a 2x teleconverter I stop down at least 2 stops (Again, if there is enough light). But on this series I wanted a smoother background so I did not stop down and left it @ f/5.6.
