The two flight shots below are a Common Hawker near Minions, Cornwall and a Black-tailed Skimmer at Breney Common. The hawker was taken by Kate Jones last weekend and the skimmer shot was taken in July by myself. To capture a dragonfly flight shot is difficult and mostly relies on a good deal of luck!
With some perserverance and a high shutter speed, it is possible to get some acceptable shots. The above shot was auto focus and the skimmer was set to manual focus. I simply waited for the insect to enter the focus area.
