I am in a mood for abstract photography this week. The shadows yesterday and today, the couple of red ornamental fish today. We were strolling in Olbrich Botanical Gardens, or rather, since it was raining, in its indoor conservatory. We probably went around the building more than five times, and each time I was discovering another interesting plant or an angle to shoot the one I already did. And yet, my favorite from the day is this abstract of koi fish. I love their bright colors, which make the subject distinguishable even under rapidly moving waters under small waterfall.
