Light on the Tulip Leaf

It is mid June and a cool, early morning. The sun, on the far side of a cluster of trees, has been above the horizon for less than an hour. On the near side of the cluster, my side, branches and leaves remain largely in shadow, but for one leaf on a tulip poplar. This leaf fans out broadly, unobstructed to the sun. Light lights it through, wholly, to a translucent green. The moment shifts, as does the sun, and the tulip leaf returns to shadow.
