I spotted this single leaf on the walkway about 7:30 AM on June 29 and thought the water drops made an interesting image. The clouds made for soft light. About 30 minutes later the sun broke through and I got the image below with stronger shadows. I decided to experiment by making the same enhancements to both images.
First I adjusted color saturation to +80.
Then I adjusted color hue to +70.
There is a lot of color hidden in what original appears to be mostly gray.
