Overlays are elements within Develop Persona which are placed on top of an image. Any adjustment applied to an overlay affects the image below.
However, overlays can have a varying level of visibility, which varies the impact its adjustments have on the underlying image. In this respect, Overlays in Develop Persona act in a similar way to masks in Photo Persona.
Areas of an overlay which are transparent ignore the overlay's adjustments, while opaque areas display the applied adjustments. Areas of semi-transparency (such as those created with the Overlay Gradient Tool) will display the adjustments by a varying degree.
The adjustments applied to an overlay are determined using the Overlays panel.
There are two types of overlay: Brush and Gradient.
