Looking up from a forest trail at a nearby nature center, I saw the leaves of a beech tree backlit by the afternoon sun. I picked off a few of the interesting ones and held them by hand so as to take some closeups. I find the patterns interesting in the same way ink blots are interesting.
What do you see in these abstract images?
Can anyone explain what’s going on here? Is this how leaves start to turn in the fall? A disease of some sort?
