Hue

One of the ways our eyes see contrast between objects in a photo is through the differences in color. Figure 7.6 shows the same image with the colors all skewed (I used Photoshop's Image > Adjustments/Hue/Saturation control and adjusted the Hue slider). It's easy to differentiate between the green sky and magenta field, isn't it? However, when this garish image is converted to grayscale, the image shown in Figure 7.7 results. It's identical to Figure 7.4. Photoshop ignores the color differences in making the conversion, as long as the colors maintain their relationships.

Figure 7.6. Changing an image to a garish color scheme doesn't affect the grayscale conversion one whit.
