How high a contrast ratio do I need?

Digitalis Education Solutions, Inc.
In a planetarium, it is somewhat distracting if the dark areas of a starfield are a dark gray rather than a full black. How black the dark areas appear depends on a number of factors, including the contrast ratio of your projector. The contrast ratio of a projector is the ratio of the luminance of a white projection compared to a black projection. Digital projectors usually have much lower contrast ratios than analog projectors, which is just inherent to the technology differences.
