I was photographing the fall forest as I began to search the ground for a new photo theme. Then I noticed that a Geometer Caterpillarami crawling on the leaves is very small, 3-4mm long. I switched to a macro lens and lit the worm from behind with a flashlight. After dozens of attempts, I was able to take a sharp picture of it.
