occasional magenta/green blotches

My experiences: ISO 100 works for better shadow but you sacrify highlights. Reducing magenta saturation or luminance in PS works for most landscapes. Handheld low light photography is limited to monochrome results without a tripod. Flash or LED is not an option with mixed light situation. The Foveon sensor seems to be very sensitive to subtile light color differences (skin tones!).
