Overview

image itself. In general, the results of an applied filter are not reversible. Image filters can be used to
correct for problems in preparing for and in acquiring the image. They also can be used to expose new
information in an image by removing or de-emphasizing other information. Any changes to the image are
logged in the image history data, which also offers a notes sections.
Tip: A record of image filters applied to an image is kept in the image's
Image History.
To get the most from image filters, it is important to understand the following features first:
Undo: Undo reverses the last filter performed on an image.
