In photography and cinematography, a multiple exposure is the superimposition of two or more exposures to create a single image, and double exposure has a corresponding meaning in respect of two images. The exposure values may or may not be identical to each other.
Ordinarily, cameras have a sensitivity to light that is a function of time. For example, a one-second exposure is an exposure in which the camera image is equally responsive to light over the exposure time of one second. The criterion for determining that something is a double exposure is that the sensitivity goes up and then back down. The simplest example of a multiple exposure is a double exposure without flash, i.e. two partial exposures are made and then combined into one complete exposure. Some single exposures, such as "flash and blur" use a combination of electronic flash and ambient exposure. This effect can be approximated by a Dirac delta measure (flash) and a constant finite rectangular window, in combination. For example, a sensitivity window comprising a Dirac comb combined with a rectangular pulse, is considered a multiple exposure, even though the sensitivity never goes to zero during the exposure.
Double exposure is a photographic technique in which two images are captured and combined into a single image.
Double exposure may also refer to:
Double Exposure is the third album led by drummer/pianist Joe Chambers with organist Larry Young recorded in 1977 and released on the Muse label. The song Mind Rain was sampled in Nas' 1994's N.Y. State Of Mind
In his review for AllMusic, Scott Yanow stated "The music is somewhat adventurous with Chambers as the lead voice on the numbers on which he plays piano; the final two performances are organ-drum duets that put more of an emphasis on Young's unique sound. This interesting session has some surprising music."
