Can you really refocus after the fact? Akvis claims they can! Akvis says Refocus Version 1.0 can improve sharpness of out-of-focus images. The program can also process the entire photo or bring into focus only the selected part to make the subject stand out against the background.
In AKVIS Refocus you can use two pencils to separate the subject from the background and adjust the settings to get the selective focus effect. There are also AKVIS presets which provide different degrees of sharpness.
To achieve a more realistic selective focus effect, you can sharp one part of the photo and blur the rest.
AKVIS Refocus is available in two versions – as an independent program (standalone) and as a plugin to a photo editor. The plugin version is compatible with Adobe Photoshop, Photoshop Elements, Paint Shop Pro etc.
