Figure 8 shows a screen capture of Adobe Camera RAW. The image in the preview area is of Seattle, Washington's, famous Ye Olde Curiosity Shop. This is the RAW, unadulterated (As Shot) image. At the top of the screen (1) are checkboxes for Preview, Shadows, and Highlights. A check in the Preview box shows the effects, in the image, of any changes made with the settings controls (2); a check in the Shadows box will paint any clipped shadows blue; and a check in the Highlights box will paint any clipped highlights in red. In the image, the blown-out sky (3) and posterization (4) problems are apparent. There is no apparent shadow clipping in this image. If there were, and if the Shadows box was checked, underexposed areas would be painted blue. A check in the Highlights box confirms the overexposure problem: the red painted areas of Figure 9 show that there is significant highlight clipping.
Figure 10 shows what happens to the image after moving the exposure slider (Figure 8) to the left and to a new exposure setting of -2.15. Some of the highlight clipping has been corrected. However, the shadows have darkened considerably as well. Figure 10 also shows that even with a significant reduction in the exposure setting, parts of the image are still overexposed. In fact, highlights in parts of the image, the sky for instance, are completely blown-out and all detail is lost--forever.
