WCMY CCDs
How come RGB CCDs are more common than WCMY CCDs? Looking over their
descriptions on the web, I would have thought WCMY CCDs would have made
RGB obsolete, not only for astronomy, but for consumer digital cameras
too. Resolution ought to be the same for both. WCMY gathers more
light. With four types of sensors, WCMY ought to give better color
balance too (after appropriate transformations).
