ISO sensitivity is the feature on digital cameras that directs the processing of light. <u>Higher ISO sensibility means more light is captured,</u> and the photography will be brighter. It can, however, introduce the noise in the photograph.
Indoors, when there is not enough natural light, ISO needs to be adjusted for higher light sensitivity. In case you are doing a window shoot during a bright day, ISO set to 500 can capture a good photo. <u>But for normal, everyday indoor usage, at least ISO set to at least 800 is likely needed to produce a clear shot. </u>When the room is darker, the ISO should be increased. ISO of 1600 should be used in a completely dark room.
