From Filter Forge:
Filter Forge Freepack 2 is a free high-end plugin for Adobe Photoshop and compatible hosts based on Filter Forge technology. It allows photographers to apply various enhancing effects to their works, such as sepia, aging or rigidity. All effects are adjustable, seamlessly tiled, resolution-independent, and support real-world HDRI lighting. Filter Forge's rendering engine takes full advantage of dual-core processors - in comparison to a single core the rendering speeds up to 96%. All filters included in the freepack are also available from the Filter Forge filter library, so the users of the 'full' Filter Forge can benefit from them as well.
