[. . . ] You can also use the Negative Image command to create a positive image from a scanned photographic negative. Use an Invert adjustment layer to create an adjustment layer that has the same effect as the Negative Image command but doesn't change the original image pixels. Use the Solarize command to produce a negative image in which you control the threshold level. This level is the lightness value above which all colors are inverted. Use this command to create interesting effects. You can create a negative of a selection or an entire image. To use the Negative Image command: Choose Adjust > Negative Image. To use an Invert adjustment layer: 1 Choose Layers > New Adjustment Layer > Invert. There are no additional settings for this adjustment layer. For information on adjustment layers, see "Using Adjustment Layers" on page 283. 3 Click OK. Chapter 8: Making Color and Tonal Corrections 201 To use the Solarize command: 1 Choose Effects > Artistic Effects > Solarize. 2 In the Threshold edit box, select a lightness threshold (1 to 254) above which all colors are inverted. At a threshold of 1, all image pixels are inverted and the effect is the same as applying the Negative Image command. 3 Click OK. Using the Histogram to Analyze Images Do I need the histogram? For image editing professionals, the histogram is a powerful tool for understanding and correcting images. For casual users, getting familiar with the histogram may not be necessary. Paint Shop Pro offers many simpler ways to adjust images. For information on how to begin correcting your photos, see "How to Approach Color, Contrast, and Saturation Adjustments" on page 53. The histogram displays a graph of the distribution of red, green, blue, greyscale, hue, saturation, and lightness values in an image. You can analyze the distribution of detail in the shadows (shown in the left part of the histogram), in the midtones (shown in the middle), and the highlights (shown in the right part) and decide how to make corrections. After you analyze the histogram, you can correct the image with Paint Shop Pro's color and contrast correction commands or you can use commands that adjust your image based on its histogram features: Equalize, Histogram Adjustment, and Stretch. To display the histogram for an image: 1 To limit the histogram data to a specific area, make a selection in the image. See "Using the Selection Tools" on page 154. 2 Choose View > Palettes > Histogram or press F7. The graph represents how many pixels are at each value of the selected channels. [. . . ] On a correctly adjusted monitor, the inner rectangles are difficult to distinguish from the outer rectangles. 3 Do one of the following: To adjust the red, green, and blue values in unison, mark the Link channels check box. To adjust the values individually, clear the Link channels check box. 4 For each color (or for all colors if they are linked), drag the slider until the inner rectangle seems to blend into the outer rectangle.
