Taking Pictures in Dimly Lit Locations
When taking pictures under low light conditions, such as during twilight or
at night, the camera shutter must be opened longer to allow more light in.
This camera comes with a special mode A (Night Scene) for taking
pictures when light levels are low. In Night Scene mode, the camera
decreases the shutter speed for optimal exposure to capture beautiful
pictures at night. You can also use this mode to take portraits with night
scenes in the background as the camera will automatically select a long
shutter speed even when using the flash.
Memo
When pictures are taken in dimly lit locations, the shutter must stay open
longer which contributes to camera shake. When using a shutter speed at
which camera shake is likely to occur, f (camera shake warning) appears
on the LCD monitor. To prevent camera shake, use a tripod and the self-
timer or remote control function.
You can also increase the ISO sensitivity setting to take pictures in dimly lit
locations without using the flash. When the sensitivity is increased, the
shutter speed also increases, making it easier to prevent camera shake and
blurring of the subject. However, noise, which appears as a grainy pattern,
may appear in the picture (p.67).
Taking Pictures of Your Pet
In Pet mode (E), choose the appropriate icon
depending on whether your pet is dark, light, or
in between. The exposure will automatically be
adjusted to produce the best picture. Choosing
either the cat or dog icon does not affect the
resulting picture. Choose whichever you prefer.
