Blow Up is a Photoshop plug-in that lets you enlarge photos to huge sizes with smooth surfaces and sharp details. The algorithms used by Blow Up are based on analysis of the contents of the image and not just on adjacent pixels. This ensures that surfaces that should be smooth are free of artifacts and that components with clear edges do not lose their sharpness.

The plug-in can be launched from the "Filters" menu of Photoshop. It can be tested for 15 days without restrictions.
