I was in my car on the way home from work, wondering what to do for today's PAD. I saw myself in the rear view mirror and said "Hey!" I didn't even make it out of the parking lot...
When I got home, I tweaked the photo in PS, adding some contrast by way of the levels control and turned it B/W by removing the green and blue channels, then saving as a grey scale image. I have the original and a color/tweaked version in my Before And After Gallery.
