One of my personal favourites.
I shot this backwards through the sunroof of a moving car. In color, this scene was largely a jumble of green and seemed a bit of a cliche, so I took it in B&W. It's probably still a bit of a cliche. I really like the way the BW shot highlights the wet branches of the redwood and drops the rest of the image into the background. I hope trees count as plants.
Picture of a rose taken on a solid surface. Leaves fade into the background. :) View in full.
