Metering If you cannot obtain suitable exposure conditions, you can change the metering method to take brighter pictures. ISO You can select the ISO sensitivity when taking pictures. The speed or specific light-sensitivity of a camera is rated by ISO numbers. NVMUJ "650 Icon Metering Mode 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 flowers 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. 038 Icon ISO Mode Description [Auto] The camera's sensitivity is automatically changed by variables such as lighting value or subject brightness. [ISO 80] [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.
