Attached is RGB image and corresponding 0 Plane of RGB. The objects in the grayscale image from the 0 Plane of the RGB image can be seen when the Image range is adjusted to (0-20). But in the full RBG image I can't see them, because the Image range runs from 0-255 for all planes. How can I independently adjust the Image Range of individual planes in the RGB Image?
Duplicate the image wave, then
imagewavecopy[][][0] *= 12  // or some nice number
I say duplicate the wave, because I have a horror of destroying original data. Work on a copy so that you can alway go back to the raw data.
