The ISO setting on a camera modifies the light sensitivity of the camera processor (the chip that captures the image). A high ISO setting brightens your image at the cost of increasing the ‘noise’ in the image. In stills photography this can be a deliberate, stylistic choice, adding a ‘grainy’ look to your images. In video, the noise moves as well and can render your footage poorly. Thanks to Gavin Ko for sending us this demonstration of the ISO settings effect on video shot on the Canon 60D DSLR camera.
