I saw this picture on my friends Facebook and was wondering how did the person "fade the color"? It seems like on the original picture,the person had a blue shirt. But then he somehow made it Black & White while keeping maybe
10% of the color. Even if it isn't Color Fading, can someone please tell me how to do this?
Blocked the face for privacyIf you look at the T-Shirt,he has some "blue light" on it.
