Creating stunning black and white images is not just setting the camera to black and white or to de-saturate the colors in post production. For me it means to look at each RGB channel which I stack in layers and carefully mask them to create the look I want. In addition a program like Silver Efex Pro II is very helpful. If you would like to dig deeper into black adn white conversion, please read Vincent Versace’s book “From Oz to Kansas.”
Enjoy and keep on photographing!
