Black-and-white photography has never been fully replaced by colored images. Long after the latter was introduced, black-and-white images continue to remain popular, thanks to its lower production cost and timeless style. Today, despite digital photography, black-and-white remains a preferred trend. There is often a nostalgic feeling evoked by these photographs. With no color, black-and-white photographs make the viewer focus on the details of the images—from the film grain to the subject matter.
