Glossary
Pixels
A pixel is the smallest unit (dot) used to make up an image. Clear large-sized
printed images require millions of pixels.
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 with a shooting lens working also as the viewfinder lens. The image of
the subject enters through the lens, reflects off of the mirror and into the
pentaprism, where focus is adjusted, then through the viewfinder lens. Pictures
are taken by framing the composition and adjusting the focus in the viewfinder
lens.
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.
TIFF (Tagged Image File Format)
A format used for saving highly detailed black and white or color image data. TIFF
image files can be handled by software programs for scanners and graphics
applications. Non-compressed image data are stored in this format with this
camera.
