ISO(i) ISO (ii)
ISO sensitivity is a measure of the camera’s ability to capture light. Digital cameras convert the light that falls on the image sensor into electrical signals for processing. ISO sensitivity can be set manually by the photographer or automatically by the camera.
By pressing the button [ISO (ii)], you can set up lower or higher the setting that you need. Depends on situation, sometimes you need to lower it(dim available light) and sometimes you need to raise it(extremely dim light).
The slow shutter speeds needed for dark interior scenes leave photographs prone to camera blur. If you raise ISO sensitivity, you can choose faster shutter speeds and reduce camera blur. This is why people say that ISO sensitivity should be raised if lighting is poor.
