What is Double Exposure Website Singapore?

Double exposure photography is a technique that layers two different exposures on a single image, combining two photographs into one. Double exposure creates a surreal feeling for your photos and the two photographs can work together to convey deep meaning or symbolism. A similar technique, called a “multiple exposure,” is when you combine more than two exposures in a single image.

The process for creating a double exposure with a digital camera is fundamentally the same, though much simpler. Both Canon and Nikon make digital cameras with in-camera double exposure settings that will help you create the effect. This setting allows you to select a base image from the memory card and take a second exposure on top of that image. The camera layers the images and adjust exposure for you.

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.
