Adjusting ISO Sensitivity (Recommended Exposure
Index)
ISO setting (speed) 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 ISO setting.
High ISO sensitivity
With high ISO sensitivity, images will be captured with an
appropriate brightness even under insufficient exposure.
However, increasing ISO sensitivity will cause images to
become noisy.
Low ISO sensitivity
You can record smooth images. However, compensation for
low ISO sensitivity will be made by slowing down the shutter
speed. You should take camera-shake or movement of
subjects into account, too.
