3 In the Levels dialog box, click Reset and we’ll try another method for adjusting
the shadows. Hold down the Alt / Option key as you drag the shadows slider
to the right to set a value of 70: just inside the left-hand end of the tonal curve.
e clipping preview shows you where the darkest parts of the image are.
4 Watch the histogram as you release first the Alt / Option key, and then the
mouse button. e histogram curve shifts to the left—possibly a little too much.
You can see that the left end of the curve has become truncated. In the Levels
dialog box, use the shadows slider to reduce the value to 45. e curve in the
histogram is adjusted so that there is minimal truncation (clipping).
5 Hold down the Alt / Option key; then, drag the highlights slider to 185. e
clipping preview begins to show significant clipping of image detail in the
brighter parts of the photo. Drag the highlights slider back to 195, where the
clipping is minimal; then release the Alt / Option key and the mouse button.
