Basic techniques for better images
Adjusting the ISO sensitivity
ISO is unit of measurement (sensitivity), estimating how much light an image pickup device
(equivalent to photo films) receives. Even when the exposure is the same, images differ
depending on the ISO sensitivity.
To adjust the ISO sensitivity, see page 49.
The apparent color of the subject is affected by the lighting conditions.
Example: The color of an image affected by light sources
The color tones are adjusted automatically in the auto adjustment mode.
However, you can adjust color tones manually with [White Bal] (page 47).
High ISO sensitivity
Records a bright image even when shooting in a dark location.
However, the image tends to become noisy.
Low ISO sensitivity
Records a smoother image.
However, when the exposure is insufficient, the image may become darker.
