Butterflies are wonderful "creatures", many of them can show two completely different sides, one more ordinary when folded. And the other one brightly colored and eye catching.
Here is a peacock butterfly in folded "mode". (ISO 100, F5, 1/1600s)
And in the following image he or she is showing all the beautiful colors. (ISO 100, F5, 1/640s)
Both images shot with Nikon D300s and Tamron 90 macro.
