With all due respect to the world of colour and colour images: some Images first make an impression in black-and-white. Close-ups of people, street scenes and sharp images of details achieve their full effect when displayed on a grey scale. When set to the BEST SHOT "Monochrome" mode, the EXILIM camera employs only monochrome filters and thus produces a black-and-white image.
Instead of special colours and their luminosity, the intent of a black-and-white photo is to focus attention on the content and the impression it makes.
