Another one of my favorite results. In this photo, the horse stands out nicely from the surroundings. The mask around the horse was constructed from a copy of the green channel layer that had been contrast enhanced. The channel mask was created by brute force with the pen tool and a brush set to overlay mode. After masking, the foliage part of the photo was taken into PhotoEffects and a "Deep Forrest" glow filter added. The horse was taken into PhotoEffects and three filters added, but unfortunately I don't remember which ones I used.
