Black and White conversion done in Lightroom. I feel sometimes monochrome images can better convey mood than color and at other times color more efficiently tells the story. Regardless, telling the story is the key to an image, not what camera or what software was used. Composition and understanding of how your camera works are far better than your cameras ability to recover shadows or print large.
