Basic techniques for better images

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 (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 38.

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 33).

Metering Mode:
Allows you to change the part of the
subject to be measured to determine the
exposure (page 36).

Correct exposure

Underexposure
= too little light
Darker 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.
