You can select the ISO sensitivity when taking pictures.
The speed or specifi c light-sensitivity of a camera is rated by ISO
numbers.
Icon ISO Mode Description
[Auto]
The camera’s sensitivity is automatically changed
by variables such as lighting value or subject
brightness.
[ISO 100]
[ISO 200]
[ISO 400]
[ISO 800]
[ISO 1600]
You can increase the shutter speed while the same
amount of light is present, by increasing the ISO
sensitivity. However, the image may be saturated in high
luminance. The higher the ISO value, the higher the
camera’s sensitivity to light and therefore the greater its
capacity to take pictures in dark conditions. However,
the noise level in the image will increase as the ISO
value increases, making the image appear coarse.

If you cannot obtain suitable exposure conditions, you can change the
metering method to take brighter pictures.

Description
[Multi]
Exposure will be calculated based on an average
of light in each image area divided into multiple
regions. However, the calculation will be biased
towards the centre of the image area. This is
suitable for general use.
[Spot]
Only the rectangular area in the centre of the LCD
monitor will be metered for light. This is suitable
when the subject in the centre is exposed correctly,
regardless of the back lighting.
[Center]
Exposure will be calculated based on an average of
the available light in the image area. However, the
calculation will be biased towards the centre of the
image area. This is suitable for taking a picture of
small objects like fl owers or insects.
 If the subject is not the centre of the focus area, do not use the spot
metering as this may result in an exposure error. In this circumstance, it is
better to use exposure compensation.
