scenes. The company introduced Kodak Panchromatic Cine Film as a regular stock in 1922. The first black-and-white feature film photographed entirely on panchromatic stock was The Headless Horseman (1922). But early panchromatic stock was more expensive, had a relatively short shelf-life, and was more difficult for laboratories to process because it required working in total darkness. Not until the prices were equalized by competition in 1926 did it become used more widely than orthochromatic stock. Kodak discontinued manufacturing general-purpose orthochromatic motion picture film in 1930. Digital panchromatic imagery of the Earth's surface is also produced by some modern satellites, such as QuickBird, Cartosat and IKONOS. This imagery is extremely useful, as it is generally of a much higher (spatial) resolution than the multispectral imagery from the same satellite. For example, the QuickBird satellite produces panchromatic imagery having a pixel equivalent to an area , while the multispectral pixels represent an area of .
