Exposure Adjusting the light intensity
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.
=too much light Whitish image
Correct exposureShutter speed = Length of time the camera receives light
Aperture = Size of the opening allowing light to pass through
ISO = Recording sensitivity
The exposure is automatically set to the proper value in the auto adjustment mode. However, you can adjust it manually using the functions below.
Adjusting EV:Allows you to adjust the exposure determined by the camera (page 31).
Allows you to change the part of the subject to be measured to determine the exposure (page 43).
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 45.
High ISO sensitivityRecords a bright image even when shooting in a dark location.
However, the image tends to become noisy.
Low ISO sensitivityRecords a smoother image.
However, when the exposure is insufficient, the image may become darker.
