ABSTRACT

As a review, exposures are the result of the total amount of light allowed to enter the camera, and the amount of light is the product of intensity and time. Of course, the amount of light needed to record an image is also based on the sensitivity of the recording media or the ISO value. Intensity is determined by the size of the lens’ diaphragm (aperture), and the time is determined by the duration the shutter (shutter speed) is allowed to remain open. Any image recorded in daylight can also be recorded in low-light conditions because these exposure principles do not change whether it is daytime or nighttime. Low-light photography merely requires patience because recording quality images in low light necessitates longer exposures.
