The most comprehensive control over the color image process is provided by the four channel LRGB technique that uses a separate luminance image to provide the resolution and detail when combined with the three color channels. Stellar Magic provides tools for LRGB imaging for images acquired either with monochrome cameras or one-shot color cameras. Even images created with the simpler RGB technique can obtain comparable results when further processed with the wavelet multiresolution filters. STACKING: Images can be stacked in either RGB or LRGB mode by the same methods used for luminance images in the Image Combiner program. Color images may be saved at resolutions of up to 96 bits per pixel in FITS format or up to 48 bits per pixel in TIFF and PNG formats. Images saved in FITS format automatically contain a complete list of the stacked files as well as all color adjustments. COLOR BALANCE: The color balance of the image can be selected from a RAW balance, where the colors are just as they appear in the data, or from pre-selected conditions of white and yellow balance, or by complete numerical specification of the individual color channels. ADJUSTMENTS: Color adjustments to the image may be made by either Hue, Saturation and Luminance (HSL) controls, or by direct histogram manipulation of the individual colors. The sharpness or smoothness of an image can be adjusted by the wavelet multiresolution control at five different scales. Wavelet sharpening usually provides greater sharpening with reduced risk of producing undesirable artifacts such as “black-eyes”. HSL HISTOGRAM WAVELET © Laser Diagnostics 2006-2009 COLOR  PROCESSING
