You should always start with basic adjustments. On the Basic tab,
click the Auto button to have ACR calculate values for the Exposure
through Blacks sliders. The tonal range isn't being fully realized, so
drag the Blacks slider to -45. Drag Clarity to +100 and Vibrance to
+57 to give the image some tropical punch (the shot was taken in
Mexico). Figure 12.10 shows the results.
3.
Switch to the Tone Curve tab. The interface is similar to the Curves
adjustment; here you can affect specific regions within the tonal
range by adjusting the sliders (see Figure 12.11). Boost the highlights
by dragging the Highlights slider to +33. Press P to toggle off the
preview for this tab. Press P again to toggle it back on so you can see
the effect of boosting the highlights.
