Channel Combination Problem

Hi, I use Channel Combination to split my color image into R, G and B channels, then use a luminance filter and apply deconvolution to it. Worked ok. After that, I use LRGB combination to create a new image from my luminance, R, G and B channels. Works but the new image is monochrome. Any ideas what goes wrong? Thanks in advance, Matt
 
i'd extract luminance from the RGB at the linear stage, rather than splitting it into its components. then process the L and RGB separately. make sure to keep the brightness of both the RGB and L images roughly the same when stretching them. then use LRGBCombination to load *only* the L image and apply it to the RGB image, making sure there is no mask active on the RGB image when you do this. it should work out properly like that.
