RAW
Refers to raw data, data which has not been enhanced with a camera option
like white balance, sharpness, contrast, etc. This file format is for viewing and
processing with our own software. You may not be able to open or process
these files with other graphics software applications, and these files cannot be
selected for DPOF printing. RAW files are assigned an orf file extension (*.orf).
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.
Single-lens reflex camera
A camera that uses the reflective mirror to bend the light entering from the
shooting lens and uses the viewfinder to check. There is no difference
between the composition to be captured and the composition viewed on the
viewfinder.
Sleep Mode
A mode designed to save battery life. The camera automatically enters the
sleep mode if you do not operate it for a certain time. To get out of the sleep
mode, use any button on the camera (shutter button, menu button, etc.).
Spot metering
The meter reading is taken from a very small area around the center of the
subject, defined by the spot metering area mark in the viewfinder. Spot
metering is ideal for use in difficult light conditions, or when the important
element of the picture (subject's face) is small. Use spot metering for backlit
subjects, or sports and stage performers. See also digital ESP metering and
center weighted averaging metering.
TFT (Thin-Film Transistor) Color Monitor
A color monitor constructed using thin-film technology.
TTL phase-contrast detection system
This is used to measure the distance to the subject. The camera determines if
the image is focused by the detected phase contrast.
TTL (Through-The-Lens) System
To help adjust exposure, a light receptor built into the camera directly
measures the light passing through the lens.
