<human>:  How do I take a clear picture in low light?
<bot>: To take a clear picture in low light, you should use a camera that has a wide aperture, such as a prime lens. Set the aperture to its lowest f-stop number, then adjust the ISO and shutter speed accordingly to achieve the desired exposure. Use a tripod to minimize camera shake and make sure the camera lens is clean for a clear image. If your camera has a flash, you can also use it to provide additional illumination in low light situations.
