Luminance while imaging luminance meters measure luminance in a way similar to the way a digital camera records color images. Luminance Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, is emitted or reflected from a particular area, and falls within a given solid angle. The SI unit for luminance is candela per square metre (cd/m). A non-SI term for the same unit is the nit. The CGS unit of luminance is the stilb, which is equal to one candela per square
A Measure of Salvation way to Earth. Simon further explains about the probe, and how the contaminated Basestar was abandoned by the rest of the Cylon fleet. Apollo realizes that the human race now has a way to exterminate the Cylons once and for all. All they need do is execute their Cylon prisoners within range of a Cylon Resurrection Ship. Captain Helo objects to this plan, arguing that exterminating an entire race would be a "crime against humanity" and make the humans no better than the Cylons. Apollo argues that the Cylons are not human and they should be wiped out. Helo retorts
