A simple painting effect.
I can't remember what program I used, but looking at the shooting date, I suspect it was using Photoshop.
E-510 with Zuiko Digital 14-54mm f2.8-3.5
54mm, f/6.3, 1/160s, ISO400
For this shot, the metering was at ESP and was not tricked by the strong backlight! I needed to ensure the shutter speed was fast enough to freeze the leaves as the wind was blowing gently; thus, increasing the ISO was inevitable. The aperture at f/6.3 was adequate to get the whole frame sharp.
