Working with Presets
The Perfect Enhance Presets are divided into two types: Corrections and Enhancements. Corrections address basic tasks like fixing common color cast or contrast problems, while Enhancements add style to an image (for example, Cool Night or Magic Landscape). To use any of these, just select the item and it will be applied after a couple seconds. To remove any preset effect, you can either use the Undo shortcut Command-Z (Mac) or Control-Z (Win), or you can click the No Changes preset in the Corrections panel.
There is also a User Presets area, which as of this writing automatically generates presets as the user modifies the settings, and then applies them to an image. Afterward, when the user returns to the preset area, there is a “Recently Used” item listed under User Presets, which can then be re-used as necessary by selecting it with each new photo you process.
