If necessary, click the Advanced disclosure triangle to show the advanced Highlights
& Shadows controls.

Adjust the High Tonal Width parameter by doing one of the following:
 Drag the High Tonal Width slider to the right to increase the tonal range of the
highlights adjustment, and drag the slider back to the left to reduce the tonal range.
 Click the left or right arrow in the High Tonal Width value slider to adjust the tonal
range of the highlights adjustment by single increments, or drag in the value field.
The left arrow reduces the tonal range, and the right arrow increases it.
 By default, the High Tonal Width value slider is set to 40.0. Double-click the number in
the High Tonal Width value slider, then enter a value from 0.0 to 100.0 and press Return.
Aperture uses the new High Tonal Width setting to determine the range of highlight
tonal values that are taken into account during a highlights adjustment. The tonal
range begins at pure white, and increasing the High Tonal Width parameter value
broadens the tonal range to include tonal values closer to the midtones.
Use the High Tonal Width slider
and value slider to adjust the
range of highlight tonal values
affected by a highlights
adjustment.
