Using Image Enhancement History
To commit or undo your image edits (one by one or all the steps), use the History panel in the
Image Enhancement window. Once you have modified the starting image, the result window
displays the changes.
Click the Apply button next to the History list to commit the change. Modifications not
added to the History by clicking the Apply button will not be actioned.
Click the Reset button to discard changes you have performed with a given tool, before
they are applied.
Click the Discard all changes button to restore the image as it was before you started the
current enhancement session.
Any time you want to see what output a certain step resulted in, double-click it in the History
list. The display shows the result of that action, removing all actions performed afterwards. If
you apply a new change to the displayed image, that replaces all changes that were made in
the History list after the chosen one.
Saving and applying templates
If you have a number of similar images to enhance, you can build up a list of enhancement
steps to apply to all of them.
To create and store an image enhancement template, first bring an image file into the Image
Enhancement window, then carry out your preprocessing steps and add them to the History by
clicking the Apply button. When you are done, choose Save Enhancement Template from the
Image Enhancement window’s File menu. Browse to your preferred destination and save the
template file (with the extension .ipp).
To carry out the set of modifications saved in the template file on another image, simply open
the new image in the Image Enhancement window and choose Load Enhancement Template
from the same File menu.
