Filter Forge is just a Photoshop plugin, a pack of filters that generate textures, create visual effects, enhance photos, process images.
Filter Forge comes with a visual node-based editor allowing you to create your own filters – textures, effects, distortions, backgrounds, frames, you name it. All filters automatically support 16- and 32-bit modes in Photoshop, real-world HDRI lighting, bump and normal maps, huge resolutions, and most filters can be seamlessly tiled.
Anyone can contribute their textures and effects to the online filter collection so it grows with every submitted filter. This means the more people use Filter Forge, the better it gets.
