Figure 1: Dinoflagellate images courtesy of Prof. Brian Matsumoto, U. of Southern California, Santa Barbara, CA. The Lucis image most clearly defines the transparent reticulum of the cell and reveals details within the dark central mass of the chloroplasts. Lucis most fully reveals the full extent of the central fissure that divides the mass into two halves and shows details, such as varicosities, within the transparent strands.
Lucis processing only effects the intensity information in an image. To process a color image, Lucis converts the RGB (Red Green Blue) information to HSL (Hue Saturation Luminance). Lucis processes the Luminance information, and then combines the new Luminance (L') with the unaltered Hue and Saturation. The HSL' information is converted to RGB. Color images may experience color shifts in patches of the image as Lucis Pro extracts the image detail. Lucis Pro has an Assign Original Image Color slider which allows you to easily repair these color shifts.
