Fill Color The Fill Color patch enables you to determine the color to use in the areas that lack image detail created when correcting for pincushion distortions. Click on this patch to access the color picker or click on the eye dropper to sample any color within an image open within Capture NX 2's editor. Correct > Color Aberration Control The Color Aberration Control tool can be used to adjust and control potential color fringes that can occur in photographs. Color aberration is caused by the various angles at which the different color wavelengths are refracted when traveling through a lens element. The result, called a color aberration, appears as a color halo on the side of an object that is positioned away from the center of the image. It is recommended that you view the image at 100% while making color aberration adjustments. It is important to review the results of the changes, especially around the corners of the image, to balance the effect. The Color Aberration Control tool provides you with the following controls: Red - Cyan The Red - Cyan slider contracts and expands the red channel to reduce either red or cyan fringing. Moving the slider to the left reduces red fringes, while moving the slider to the right reduces cyan fringes. Blue - Yellow The Blue - Yellow slider contracts and expands the blue channel to reduce either blue or yellow fringing. Moving the slider to the left reduces blue fringes, while moving the slider to the right reduces yellow fringes. Chapter 20 - Adjust Menu | Correct > Color Aberration Control 203
