A lazy day at the lake and not much to photograph until I saw the wind play with the leaves of that japanese maple tree (acer japonica). Here in Europe they are quite popular in the gardens because of that wonderful red of their leaves even in the midst of summer.
The image alone I found not interesting enough, but that development from the static leaves, suddenly showing their bright underside in a gust of wind and heavily shaking when the wind becomes still stronger, that was it for me.
