It is not "Intensity", It is Luminance[edit]

In the Derivation part, FB(x) and F(x) are not intensities. They are luminances! And the reason the equations come in that form is due to an assumption: the attenuation coefficients for lights with different wavelengths are the same. — Preceding unsigned comment added by (talk) 13:10, 14 October 2013 (UTC)

Bug report: disambiguation[edit]

Sorry for not fixing this myself, don't have time at the moment, but maybe this comment will help: This article doesn't link to uses of the term 'Visibility' in any field except meteorology. There should be some disambiguation, either on top of this page or on a separate page. —Preceding unsigned comment added by (talk) 01:32, 5 August 2008 (UTC)
