As promised, here is the second edition of River Portrait. This is an image of Jeff Leopold exiting a pool on the Stordal River in Norway. The original photo was very dark (taken around 11:30pm) but I was able to extract the data that I wanted which was the land of the midnight sun glow. I then tweaked it with Adobe Illustrator. Click on the image for a closer view.
