The master portrait photographer Yousuf Karsh made the black background his signature, making iconic portraits of Ernest Hemingway, Pablo Picasso, Andy Warhol and Muhammad Ali, among many others, all on a black background. Karsh preferred black because it forces the viewer to look at nothing but the subject of the portrait, with no distractions. Headshots on a black background convey distinctiveness and sincerity, and work best for dramatic, high impact brands that want to stand out for looking good.
