What Does the ISO Setting Do when Using a Samsung Camera?


The ISO setting number indicates the camera's sensitivity to light. The higher the ISO number, the greater the sensitivity to light.

If the ISO is too low in dim lighting conditions, photos tend to be blurrier, like the top photo.

While a higher ISO setting allows better photos in low light, too high an ISO setting can cause photos to appear grainy. Try varying the ISO setting to discover the best settings for different lighting conditions.

When changing the ISO setting, remember:

  • Increase the ISO number setting for clearer photos in dim light or near darkness areas.
  • Decrease the ISO number setting for clearer photos in normal or bright light area.

The camera will set this number automatically when the ISO setting is set to Auto.

Every camera is different, so for specific instructions, such as how to change the ISO setting, shutter speed, or aperture settings, refer to your camera's manual.
