Project page · Code · Video

How to use. (1) Upload a photograph, or pick an example below, and press Restore: one-step diffusion restores the all-in-focus image once. (2) Click the restored image to set the focal point; each click runs only the 1.3M-parameter renderer. (3) Drag the blur strength, or switch to Two focal planes and click two points to keep both sharp.
