The amount of light in our homes may appear sufficient to our eyes as they
automatically adjust. To a camera however, it's not nearly enough to make a proper
exposure. Birthday parties are a great example as the lights are turned off for the cake
and candles. In these low light situations, you'll often benefit from an ISO of 1600 or
3200. With the camera able to collect the existing light faster, a quick shutter speed of
1/250 can be used to freeze the child's movement.
