Hackberry Emperor (48)
|Tonight I decided to give you a more "artistic" presentation of a butterfly. This is the Hackberry Emperor perched on Oakleaf Hydrangea blooms. Photo was taken at a local botanical garden. The butterfly was in bright sun against a light colored brick wall. I was worried about over-exposing the white flowers, so I used manual mode and underexposed by (-1.0). |
