Increasing the exposure time, without adjusting any other settings, will make your picture brighter, as it increases the amount of time that the shutter remains open while the image is being made (letting in light for a longer period of time). While you might think that this would be a good way to brighten-up the picture, it is also a good way to get a blurry image if the camera is hand held, as there's an increased time period in which any movement of the camera can screw-up the image.
