The Sources panel provides a means of storing multiple clone sources that you can use in conjunction with the Clone Brush and Healing Brush tools.
About the Sources panel
The Sources panel is available from the Photo Persona; it can be switched on via View>Studio.
The panel lets you set up multiple global sources and define the "pickup" area for each source, in advance of (or during) cloning, healing, or patching. After a Focus Merge or HDR Merge, the panel will also automatically appear.
To add a global clone source and define its clone area:
Open an image, then from the Sources panel, click Add Global Source.
Double-click on the newly created source entry, then hover over the area of your document you wish to set as a clone source and click once.
To clone from a clone source:
Ensure you have either the Clone Brush tool or Healing Brush tool selected.
On the Sources panel, make sure the Toggle Source Preview option is disabled. Your current document that you wish to edit should be displayed.
Select a source from the Sources panel list.
Hover over your document; you should see a preview of the clone source area. Simply click once or click-drag to begin cloning or healing.
The following settings are available in the Sources panel:
Toggle source preview—when enabled, allows you to cycle through and preview each source. Disable to return to editing your current document.
Add Global Source—Makes the currently active document a global source, which gets added to the bottom of the panel. When the source entry is selected and preview is enabled, you need to define a source area for that source before it can be used to clone from.
Delete Global Source—deletes the currently selected global source.
