[. . . ] Double-click the number in the Brightness value slider, then enter a value from –2. 0 to 2. 0 and press Return. •• Use the Brightness slider and value slider to lighten and darken the photo. A value below 0. 0 decreases the brightness of the image. A value greater than 0. 0 increases the brightness of the image. The brightness of the image is updated as you change the parameter value. Working with the Enhance Controls An Overview of the Enhance Adjustment You use the Enhance adjustment controls to set the contrast, definition, saturation, and vibrancy, as well as the black, gray, and white tint values. You can also brush the Enhance adjustment on selected parts of an image. For more information, see An Overview of Brushed Adjustments on page 388. Chapter 17    Making Image Adjustments 338 Adjusting Contrast in the Image If you want to adjust the difference between the dark and bright areas of the image, you can modify the Contrast parameter. An image with very little midtone tonality is considered to have a lot of contrast, whereas an image with considerable midtone tonality is considered to have minimal contrast. Often, an image with too much midtone tonality looks flat. Adding contrast to the image can add depth to it. However, you add contrast to the image at the expense of detail in the midtones, so a little contrast goes a long way. Before Contrast adjustment After Contrast adjustment To adjust the contrast in an image 1 Select a photo. 2 In the Enhance area of the Adjustments inspector or the Adjustments pane of the Inspector HUD, adjust the Contrast parameter by doing one of the following: •• •• Drag the Contrast slider. Click the left or right arrow in the Contrast value slider to change the contrast of the image by 5 percent increments, or drag in the value field. In addition, the Vibrancy parameter takes skin tones into account, leaving them untouched. This allows you to take a portrait and desaturate the image except for the skin tones. Before Vibrancy adjustment After Vibrancy adjustment (reduced saturation except for the skin tones) To adjust vibrancy in an image 1 Select a photo. 2 In the Enhance area of the Adjustments inspector or the Adjustments pane of the Inspector HUD, adjust the Vibrancy parameter by doing one of the following: •• •• Drag the Vibrancy slider. Click the left or right arrow in the Vibrancy value slider to change the saturation of the image by 5 percent increments, or drag in the value field. Double-click the number in the Vibrancy value slider, then enter a value from –1. 0 to 1. 0 and press Return. •• Use the Vibrancy slider and value slider to add smart saturation to the photo. A value below 0. 0 decreases the color saturation in the image, and a value above 0. 0 increases the saturation of the nonsaturated colors. A value of –1. 0 removes all color from the image, making it grayscale except for any skin tones. Chapter 17    Making Image Adjustments 342 Setting the Tint of Black, Gray, and White Values in the Image You use the Black Tint, Gray Tint, and White Tint color wheels when you want to selectively remove color casts from the shadows, midtones, and highlights in the image. Color casts are often caused by shooting in mixed lighting and unnatural lighting situations, where the difference in the color from the mixture of multiple types of source lights can produce a color variance in a specific tonal range in an image. For example, when shooting indoors, interior incandescent (tungsten) lighting can often produce a yellow color cast through the white colors in the image. Using the White Tint eyedropper, you can have Aperture isolate the highlights and add blue to the white values, thereby reducing the yellow color cast and returning the whites to neutral white. There are two methods for selectively adjusting the tint values in an image: you can use the Black Tint, Gray Tint, and White Tint eyedroppers to have Aperture automatically adjust the tint to neutral color values, or you can use the Black Tint, Gray Tint, and White Tint color wheels to manually adjust the tint values. The method you choose is determined by the level of precision you require.
