I don't usually carry my dSLR with me (since I work as a copywriter), but I had been asked to take some portraits the day I saw this leaf. I arrived early and found myself with my camera and some free time. The morning sun was also rather nice, and it lit the leaves nicely, bringing out all the veins. This was the best from a series of pictures that day.
I decided to process the image as a black and white one with high contrast so the flowing lines could have their day.
