One oak leaf back lit by the morning sun - it doesn't get much simpler than this. Since I was shooting into the sun, the challenge was to find shade for the lens to avoid lens flare. From the sunny side, this leaf looked dull. But with the sun shining through it, the leaf came to life - which is a bit of an irony for a leaf about to fall.
