Operation Manual

An Overview of Brushed Adjustments
In Aperture, you brush an adjustment when you want to specify the area of the image
the adjustment is applied to. Most adjustments in Aperture can be brushed on images.
You simply specify the parameter settings for an adjustment, previewing the effect of
the adjustment on the entire image, and then you choose to either brush the adjustment
“in” or brush the adjustment “away” using the adjustment’s Action pop-up menu.
You brush an adjustment in when you want to apply the adjustment to a specific portion
of the image rather than the whole image. When you choose to brush an adjustment in,
the adjustment is applied to specific portions of the image as you brush it on.
A plus sign (+) indicates
that you’re brushing
the adjustment in.
You brush an adjustment away when the area you want to apply the adjustment to is
larger than the area you don’t want the adjustment applied to. When you choose to brush
an adjustment away, Aperture applies the adjustment to the entire image, and you use
the eraser brush to remove the adjustment from the areas of the image that don’t need
the adjustment.
A minus sign (–) indicates
that you’re brushing
the adjustment away
(erasing).
