Basic LRGB Combination

The Mix LRGB & Hue tool can be used to mix color from monochrome or color images. The goal of this example is to combine L, R, G, and B components from an ST-10. Since the LRGB filters do not balance red, green, and blue the Mix LRGB and Hue tool is used to scale green by 1.20 and blue by 1.33.

The Mix LRGB & Hue tool assumes that the components have already been aligned as shown by the Align DSLR, one shot color CCD, and CCD Color Component example.

Step 1 - Open the Component Images and also the Color | Mix LRGB and Hue Tool

Open the L, R, G, and B components and the Color | Mix LRGB and Hue tool. This example use Mix LRGB and Hue to mix the LRGB components before a stretch of the component data is performed. The Mixing H-alpha and Color from a DSLR or OSC CCD example applies the initial stretch before the data is mixed into a color image.

Step 2 - Select Source Color Components

Press the Select All Open button to select all of the open images. You could also check the Select Source Image Box and left-click on the image area of the source image to select a single image. The small light gray image in the tree to the left of each source image indicates that the source image is a monochrome luminance image.

Step 3 - Map LRGB in the Combination Image

Left-click on the red source image in the tree then from the Map Color control group select to R. Press the Add button to and the color map. Now add blue, green, and luminance. Set the scale factor of the green map to 1.20 and 1.33 for the blue map.

Step 4 - Build the Color Combination Image

Press the Apply to build the color combination image. The Minimize button was used to minimize all of the narrow band component images.

Step 5 - Test the Color Combination Image

Press the Release Combination button to release the color combination image from Mix LRGB and Hue. Apply digital development or other stretch to test the color combination. Edit the Mix LRGB and Hue color component tree and test as necessary.
