Insects a Challenging but Rewarding Subject


posted on 7th of may, 2009

Insects are an especially challenging subject to photograph for several reasons. They're small and flighty, which poses a need for balance between depth of field and fast shutter speed while trying to get close enough for a full-frame shot without startling the subject out of its momentary repose.

For the butterfly pictured, a Zephyr Anglewing (Polygonia gracilis zephyrus) subspecies of the Hoary Comma (Polygonia gracilis), I found such a balance by taking advantage of the bright midday sunlight.
