[. . . ] If that image is later processed in Capture NX 2, Active D-Lighting will be applied to brighten the shadows and create the appropriate levels of tonality throughout the image, resulting in an image in which details are present in both highlights and shadows. This functionality is provided in addition to the D-Lighting functionality found in the Adjust menu. You can use the provided pull-down menu to modify the amount of Active D-Lighting applied to your image. Choose from the following options: Unchanged This option reverts back to the setting used within the camera when the image was captured. Off This option prevents any Active D-Lighting from being applied to the image. Low This option applies a low level of Active D-Lighting to the image and is recommended for images shot with very high ISO. Normal This option applies a moderate level of Active D-Lighting to the image and is recommended for the majority of images. High This option applies a high level of Active D-Lighting to the image and is recommended for images shot with low ISO. 136 Chapter 15 -- Edit List | Develop Section Quick Fix Tone Curve The Tone Curve tool provides you with a curve editor that controls the tonality of the image. Within the Tone Curve tool, you are presented with a curve that enables you to control the relationship of input luminosity values to output luminosity values. Click anywhere on the curve to add an anchor point. Move the anchor point to alter the relationship of input and output values. Moving a point up makes objects of that value brighter, while moving a point down makes objects of that value darker. The curve is automatically adjusted to ensure a smooth transition between each point added to the image. Anchor points can be removed by simply clicking and dragging the anchor point outside of the curve editor or by clicking on an anchor point to select it and pressing the delete key. The Tone Curve tool provides you with the following additional controls: White and Black Output Slider These two sliders enable you to set the maximum and minimum brightness levels of the image. By dragging the white output slider down, you darken the lightest luminosity level in the image, and by dragging the black output slider up, you lighten the darkest luminosity level in the image. These two sliders are often used if the darkest and lightest colors in the image should not be pure white (255, 255, 255) and pure black (0, 0, 0). Black Point Slider Move the black point slider to the right to set all luminosity values from the point you have selected to the left to complete black. This will redistribute all of the values to stretch the luminosity range to match the entire possible range of values. It is recommended that you move the black point slider all the way to the right to match up with the left-most information from the displayed histogram. This adjusts the current image so that the darkest values in the image match the darkest value that can be displayed in a digital file. Mid-Point Slider Move the mid-point slider either to the left or to the right in order to lighten or darken the mid-tones of the image. Chapter 15 -- Edit List | Develop Section 137 White Point Slider Move the white point slider to the left to set all luminosity values from the point you have selected and to the right to complete white. [. . . ] Mid-point cannot be sampled for a single channel; regardless of the channel currently selected, sampling the image for mid-point always sets the mid point for all channels and displays the master channel. Gamma Gamma (also written "") is a fundamental property of video systems which determines the intensity of the output signal relative to the input. When calculating gamma, the maximum possible input intensity is assigned a value of one, and the minimum possible intensity (no input) is assigned a value of zero. Output is calculated by raising input to a power that is the inverse of the gamma value (output = input (1/ )). [. . . ]
