Imagine yourself under a starry night sky. Wouldn’t it be great to capture the Milky Way to show it at home or on the web? Unfortunately, you are left with a black frame after you’ve pointed the camera upwards at settings you are used to. It's time to open up the aperture, lengthen the exposure, and bump up the ISO. You will introduce noise, but do you really care? Aren’t there tools out there to reduce noise but still keep the detail?
