Set the image’s blacks
Shadow detail and the importance of visual elements in shadow vary from image to image.
In addition, some cameras are more capable of capturing shadow details than others. In some
photos, such as an image of a person’s face in the shadow of an alley, the shadow is the most
important visual element. In other photos, the details in the shadows have nothing to do with
the main subject. For example, the shadow area of the image may obscure trash that would
otherwise ruin a pristine image. In Aperture, you use the Black Point parameter controls to
increase the threshold of shadow details in the image as well as crush the blacks when necessary.
Note: The Black Point controls aren’t available for RAW decoding versions 1.0 and 1.1. To make the
Black Point controls available, reprocess the image. For more information, see
on page 334.

In the Exposure area of the Adjustments inspector or the Adjustments pane of the Inspector
HUD, use the Black Point parameter controls to recover or supress shadow detail.
Use the Black Point slider
and value slider to set
pure black in the photo.
Decreasing the value increases the amount of detail in the shadow areas by moving pure black
below the current black point. Increasing the value decreases the amount of detail in the shadow
areas of the image, effectively crushing the blacks by moving pure black above the current
black point.
