Papilio demoleus
Blenheim Palace has an area called the Pleasure Garden that features a maze, miniature buildings and a butterfly house, among other things. We went in the butterfly house to get out of the rain. This was taken hand held using the TG-4's focus stacking mode which takes 10 exposures at different focuses and merges them in camera. They don't always come out this good, especially on a subject where you cannot brace your hands or the subject is moving or whatever. Sometimes, like here, they come out great.
