Definitions for "Manual Exposure"
Manual exposure is a camera mode which is non-automatic, and requires the photographer to set their own aperture and f-stop for each shot. This mode does not rely on the cameraâ€(tm) s internal metering system, but requires you rather to take a reading with a separate flashmeter to determine correct settings. When using external flash units, your camera should be adjusted manually.
Optional mode on automatic cameras. The user selects both the shutter speed and aperture either following or ignoring the camera's recommendations to achieve the desired exposure.
A nonautomatic mode of camera operation in which the photographer sets both the aperture and the shutter speed.
