Using Fill-in Flash in Wildlife Photography

My passion in photography is for wildlife photography. This summer I have been concentration on taking pictures of insects, especially dragonflies and butterflies. In my macro work I usually use fill-in flash set to -2/3. This gives that bit of sparkle and lightens up the shadows. I include 4 examples below but many more can be found on my website in the Latest Images section of the gallery pages at mikepickwellwildimages .
