AKVIS Refocus improves sharpness of out of focus images. The program can process the entire photo or bring into focus only the selected part to make the subject stand out against the background. It's also possible to add bokeh and lens blur effects to your photos.
The software works in five modes: Refocus, Tilt-Shift, Iris Blur, Motion Blur, and Radial Blur.
