When using the filters and because they block IR, do I need to make a luminance layer? Sorry if it is off topic and if it doesn't make sence.

cant see why you MUST have a luminance layer,, RGB should work, a lot of people do say however a lot of detail is contained in the luminance layer, the ir factor is fairly irrelevant i would have thought, as with all my imaging i remove it.
