Introduction Getting Ready Taking Pictures Playback Set Up
Infinity
Once the subject of a photograph is further than a set distance away from the camera lens, moving still further
away requires no adjustment to the focus. The distance at which the subject is so far away that no change in
the focus occurs is referred to as "infinity".
ISO (International Organization for Standardization) sensitivity
This is a number that indicates the sensitivity of film to light, with higher values indicating greater sensitivity.
Film with higher ISO sensitivity is more sensitive to light and can be used to take pictures in low-light conditions,
but is also more susceptible to unwanted specks on the image (noise).
JPEG (Joint Photographic Experts Group)
This refers to an image data compression format. The compression ratio is variable, with higher compression
ratios giving smaller image file sizes but poorer image quality.

Memory Card

A recording medium on which data can be written, erased and rewritten. SD memory cards and Multimedia
cards can be used with this camera.
PictBridge
This is a printing standard that allows images to be printed directly from a digital camera or video camera via a
USB cable, regardless of the manufacturer or model.

Red-eye effect

When a flash is used to take a picture of a person, the light of the flash reflecting from the back (retina) of the
subject's eyes has the effect of making them appear to glow red. This camera is equipped with a red-eye
reduction function to prevent this effect.
Shooting mark
The "Z" mark displayed on the LCD monitor when the camera is ready to take a picture.

Shutter speed

This refers to the length of time that the camera's shutter (a curtain behind the lens) opens when a picture is
taken.
Subject
This term refers to the person or object photographed by the camera. In portrait shots, the subject is the person.
In shots of landscapes, the subject is the scenery.
