z Adjusting ISO Sensitivity (Recommended Exposure
Index)
ISO sensitivity is a speed rating for recording media that incorporates an image sensor that
receives light. Even when the exposure is the same, images differ depending on the ISO
sensitivity.
High ISO sensitivity
Records a bright image even in dark locations while increasing
shutter speed to reduce blur.
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.
