Basic techniques for better images
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.
To adjust the ISO sensitivity, see page 43.
Hints for the exposure value (EV)
When shooting a whitish overall image such as a backlit subject or a snowy scenes, the camera judges
that the subject is bright and may set a darker exposure for the image. In such cases, adjustment of the
exposure in the + (plus) direction is effective.
When shooting a darker overall image, the camera judges that the subject is dark and may set a brighter
exposure for the image. In such cases, adjustment of the exposure in the – (minus) direction is effective.
You can check the exposure referring to the histogram chart. Be careful not to overexpose or underexpose
your subject (giving a whitish or darkish image).
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.
