LRGB filters are used to produce color images in combination with an imaging device such as a camera. You collect images through each separate filter and then combine and process in software to produce a color image. The “L” filter is not color specific and is generally utilized to provide the actual detail in your image while the RGB filters are used to provide color to the image. Please see the curve graphs for exact specifications on these excellent filters.
