Iso; 03 Exposure Compensation - Samsung NV40 User Manual

ISO

You can select the ISO sensitivity when taking pictures.
The speed or specific light-sensitivity of a camera is rated in ISO numbers.
ISO menu is available in the Program and Manual mode.
- AUTO :
The camera's sensitivity is automatically changed
by variables such as lighting value or subject
brightness.
- 80, 100, 200, 400, 800, 1600, 3200 :
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 greater is the camera's sensitivity to light;
therefore it has a greater capacity for taking pictures in darker conditions.
However, the noise level in the image will increase as the ISO value
increases, making the image appear coarse.
 When the [M. CAPTURE] menu is selected, you only can select ISO AUTO,
400, 800, 1600, 3200.
 When the ISO 3200 menu is selected, the image size is fixed as 3M.
