Low light photography pushes limits. It pushes the limits of technique, demanding constant attention to steadying the camera, subject movement, and changing camera settings to suit the conditions.
In order of priority for human perception, the midtones of an image are naturally the most important as they usually contain the most detail, but they are followed closely by highlights, with shadows in last place.
In one important sense, low light photography is not just another situation, or just another themed area of photography. It carries with it a challenge; that in order to work in these lighting conditions you are forfeiting predictability.
