Image Processing Reference
Figure 2.13 This image needs more shadow detail. By turning on the Shadows clipping warning, I can see
when I've gone as far as possible.
Figure 2.14 The bright blue spots (at bottom right and along
the riverbank) indicate areas that have lost all detail and will
display as pure black.
Figure 2.15 Clipped highlights are displayed in bright red
when the Highlights checkbox is selected.
Not every image needs to have the maximum shadow and highlight detail,
though. Some images, such as low contrast images like a foggy landscape , would not
benefit from both of these adjustments. I'll cover these types of images later, but for
now it's good to know how to verify that your image isn't going beyond the limits of
what you can display or print.
