155 Chapter 22 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. Once you are satisfied with the resulting effect from the Color Aberration Control feature, click OK. You can cancel this feature at any time by clicking on the Cancel button. To reduce pincushion distortion, drag the Control Slider to the right. To reduce barrel distortion, drag the Control Slider to the left. When correcting a significant amount of pincushion distortion, the resulting image may become smaller than the original image. If this occurs, Capture NX will automatically fill the portion of the image frame that no longer contains image information with white. You can use the Fill Color pop-up Menu to select a different color to fill into these areas. Distortion Control Once you are satisfied with the resulting effect of the Distortion Control feature, click OK. You can cancel this feature at any time by clicking on the Cancel button. Adjust Menu The Distortion Control feature provides controls to reduce both pincushion and barrel lens distortions. Pincushion distortion normally affects images shot with wide-angle lenses and results in image details appearing as though they are being pulled into the center of the image. Barrel distortion, the opposite of pincushion distortion, normally affects images shot with telephoto lenses and results in an image that appears to have details that bow outward away from the center of the image. Pincushion and barrel distortion are more apparent at the edges of images. Opacity Mixer The Opacity Mixer provides you with the ability to blend the current enhancement, or to blend the effects of all of the same type of control points, with the rest of the image. For a complete description of the functionality of the Opacity Mixer, please see page 61. Once you have selected the Channel, the Blending Mode, and the opacity for the channels for the current enhancement, click OK to accept the Opacity Mixer's effect. Click Cancel to prevent the Opacity Mixer from affecting the image.
