onOne Software has release a free version of Perfect Effects 4. The software package can be accessed as a plugin through Lightroom, Aperture or Photoshopor and also as a standalone application. This free version contains only 73 of the 401 presets found in the full version but most of the power of this plugin is still there. You can combine effects by stacking them to create masterpieces. Use the masking controls or paint in the effect to apply it to only the areas you want.
When you download Perfect Effects 4 Free, you’ll also get the Perfect Layers module so you can combine images and work with multi-layered files without Photoshop.
