z Adjusting Gain/ISO Sensitivity (Recommended
Exposure Index)
Gain/ISO setting is the sensitivity to light of recording media that incorporates an image
sensor that receives light. Even when the exposure is the same, images differ depending on
the Gain/ISO setting.
High Gain/ISO sensitivity
With high Gain/ISO sensitivity, images will be captured with
an appropriate brightness even under insufficient exposure.
However, increasing Gain/ISO sensitivity will cause images to
become noisy.
Low Gain/ISO sensitivity
You can record smooth images. However, the shutter speed
may slow down to compensate for low Gain/ISO sensitivity.
You should take camera shake or movement of subjects into
account, too.
