128 LESSON 4 Image Editing Basics

First you’ll adjust the overall exposure and contrast; then, set the white and black

points to avoid clipping at the ends of the histogram before tweaking the highlights

and shadows to bring out as much image detail as you can.

1 Press the letter O on your keyboard to activate the white clipping warning;

then, keep an eye on the histogram as you drag the Exposure slider slowly all

the way to the right. e red areas that appear in the preview warn you which

parts of the image are being clipped to white.

2 Drag the slider to the left until all the red areas disappear—even from the

woman’s head-band;. e Exposure control doesn’t cause white clipping until

the setting is extreme; for now, set the Exposure value to +0.5.

3 Watch the histogram as you drag the Contrast slider through its full range,

before setting it to a value of +50.

4 Put the Whites slider through its paces. White clipping is already beginning to

appear when the setting reaches +15. Return the Whites to a zero setting.



Note: The values at

which clipping appears

may diﬀer slightly for

you , depending on

where you clicked with

the White Balance tool.
