This is one of the hubs from the felled horse chestnut tree.
I used the Camera+ app for this shot so I could split the focus point (the bud) from the exposure point (low down in the frame in the darker area).
In the next step, I used Photogene2 to make the colours more vivid by applying one of the standard colour filters. I then rotated the bud to a more interesting angle. The final step was to crop the extra trees from the shot.
here is the original shot
