We added 3 more cool photo effects for the artistic minded folks:
1) http://funny.pho.to/blue_only/ – leaves only the blue color in your photos. All other colors become black and white (great for emphasizing the blue eyes).
2) http://funny.pho.to/green_only/ – leaves only the green color and its shades in your photos. All other areas become black and white, too.
3) http://funny.pho.to/red_boost/. This effect emphasizes the red color in your photos, and also leaves the skin color untouched. All other colors become black and white. This creates a kind of retro look in your photos.
Feel free to experiments and share your photo effects with us!
