Enjoying the camera
You can create various images by adjusting the exposure and the ISO sensitivity. Exposure is
the amount of light that the camera will receive when you release the shutter.
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.
