Blue Dasher Dragonflies

A couple of images of Blue Dasher Dragonflies. The Featured Image of the male Blue Dasher was taken with a 400mm DO lens with a 1.4X Teleconverter @ f/8 on a Canon 1D mkIV. To get the smoother background I wanted I only stopped down 1 more f/stop to f/8 since I already lost 1 stop with the 1.4X Teleconverter attached. My usual workflow when (on bright days) using teleconverters for a little more sharpness is to stop down at least 1 additional stop when using a 1.4X and at least 2 stops when using a 2X teleconverter. If I am using a 3X Teleconverter I would stop down 1 or 2 more stops than when using a 2X Teleconverter if I could. But then again a 3X Teleconverter usually is so bad I would just stack a 1.4X & 2X teleconverter. If using an extension tube on Telephoto lenses to get closer focusing I would also stop down at least 1 or 2 more stops for more depth of field.

Extreme Methods To Photograph Distant Dragonflies

This is a series of some Blue Dasher & other Dragonfly images I shot over a few years using a technique for getting softer smoother backgrounds for dragonflies that you can not get close to photograph. Depth of field is limited with this technique, but I like the softer backgrounds which makes the detail in the dragonfly stand out. The subject Dragonflies are about about 5 to 9 feet away. Usually they are on a plant or branch in or over the water. Plus I get closer up images not needing a large or any cropping. I was using a Canon 400mm DO lens with a 1.4x teleconverter(s) and extension tubes to get closer focus on the small (about 1.5 inches long) Dragonflies. Basically converting the lens to only closer focusing capability. Sometimes I would setup the equipment with the lens, then extension tubes, the teleconverter and then camera. Or have the lens, teleconverter, extension tubes, then camera body. Different arrangements of extension tube(s) & teleconverters gives different “focus zones”. Depending on the width & position of the extension tubes used is how close you can focus on your subject. With all the added converter(s) & extension tubes you may loose autoexposure so I mainly set exposure by looking at a preview shot or histogram and adjust exposure from there. It takes a while to get consistent results because there are so many variables. But it works well once you get used to it. Many times I use fill flash to help light the subject because I loose so much light with certain combinations of teleconverter(s) and extension tubes.

Image somewhat soft on the bottom of the image from shooting through plants that were in the way, but liked the image anyway!
