What is Enhance detail
Enhance detail in Photoshop improves sharpness and brings out detail in areas created with Generative Fill, helping generated variations blend more seamlessly with the surrounding image.
How to apply Enhance detail
Select a large area of an image and apply Generative Fill. Go to the Properties panel and hover over any of the generated variations to view the Enhance detail icon on that variation. Click that icon to create a similar variation with improved detail and sharpness. Click back and forth between the original and enhanced variations to see the difference, and select the one you like best.
