Chapter 6. Optimizing Grayscale Images > Levels Is the Solution

Levels Is the Solution

The Levels dialog box (choose Image > Adjustments > Levels) is the cure for most common complaints about grayscale image quality (Figure 6.4). It offers you far more control and feedback than Brightness/Contrast. Instead of having only two sliders to adjust, Levels offers you five, as well as a bar chart that indicates exactly what is happening to the image. And unlike the sliders in Brightness/Contrast, the Levels sliders don't change the entire image in equal amounts.
