S (Shutter Priority) Mode
Also called Shutter Priority AE mode. The user selects the shutter speed and the
camera automatically varies the aperture so that the picture is taken with the best
exposure.

flashes in phase with the flash on the camera and can be used for lighting
techniques, such as changing the way shadows are cast on a subject.
Sleep Mode

mode if you do not operate it for a certain time. To exit the sleep mode, use any
button on the camera (shutter button, arrow pad, etc.).
TFT (Thin-Film Transistor) Color Monitor

receptor in the camera as it passes through the lens. A signal is then sent to adjust
the external flash intensity.
