When it comes to describing photographs, "black-and-whites" is a common term used to refer to images that are strictly black and white or monochrome. However, there are numerous synonyms for this term, such as "monochromes," "grayscale images," "black and grey," "black and silver," "black and white prints," and "duotones." Each of these terms alludes to the same concept of photographs that lack color, but with a unique twist. "Duotones," for example, references photographs that use two different colors to achieve a monochromatic effect. Similarly, "black and silver" might suggest a hue of metallic gray. Despite their subtle nuances, these synonyms are all interchangeable with "black-and-whites" and enhance the richness of descriptions for monochrome photographs.
