The ISO setting on your camera is important because it adjusts the sensitivity level of the camera's photo sensor. Normally you will want to leave it at the lowest setting, since this will result in better-looking photos. But in low-light situations, you may find it necessary to increase the ISO setting to get a sharp picture. However, increasing the ISO setting usually adds "noise" to your images, which is visible distortion that becomes noticeable in images.
Instructions
1. Find the ISO selector on your digital camera. Advanced cameras often have an ISO adjustment button directly on the camera body. Locate and press the "menu" button.
2. Select the "shooting" menu inside the main menu. This is often represented by an icon that looks like a camera.
3. Review your choices. The shooting menu usually has options such as white balance, scene and ISO. Select ISO.
4. Choose an ISO value. You will typically be given options such as 100, 200, 400, 800 and sometimes up to 1,600 or beyond. Select the number you desire. Each increase represents a doubling of the sensitivity of the image sensor. Select the lowest ISO number that will still allow a fast enough shutter speed to produce a sharp image.
5. Leave your ISO set to the lowest number by default and raise it only when you cannot otherwise get a fast enough shutter speed to produce a sharp image.
