I've been experimenting more with processing high-altitude HRSC two-color (GB) limb scans. I want to emphasize that these aren't geometrically-controlled or accurate color images. Basically I warp the blue channel image to overlay the green channel image, then partially subtract the blue channel image from the green to come up with a synthetic red channel. Since there's a lot of along-track motion between images, the color of the atmospheric haze structure doesn't come out too well, so I either paint it a single color, or maybe paint individual layers if there's enough color information for it. The shape of the limb is distorted in the original images (usually one half will have a different slope than the other), and this is semi-subjectively adjusted so that the horizon fits the outline of a circle of an arbitrary radius while craters near the bottom of the image are more or less round. So don't wander off and try to use these for science tongue.gif
