Macro-photography is a way for me to get outside and look for insects to photograph. Butterflies, bees, moths, spiders, and anything small and interesting will do. The equipment that I use includes a Sigma 180mm Macro lens, two flash units and often a doubler adapter. When using the doubler it is critical to set the shutter speed and the flash power properly to achieve the proper lighting.
I prefer to set everything in manual mode, and get the light readings from a hand held light meter.
The real difficulty in Photographing insects is: finding one, getting close enough, focusing on the eyes, getting proper depth of field, and staying steady before the subject leaves. Insects have great vision, and many insects can sense shadows, movement, and even air pressure change.
Below are quick samples of my Macro Photos.
