Reflecting differences

These two photos were taken a few days apart at about the same time (at the same spot). Despite having cooler and more rainy weather the first day, there was no wind, so the water was perfectly still. On the second day, it was about 35 degrees Celsius, but there was more of a breeze, so the water didn't produce the same perfect mirror effect as it did the first day. These pictures were both taken while standing on a boulder on the edge of a small pond created by storm water draining.
