Filter Forge is a high-end plugin for Adobe® Photoshop® allowing computer artists to build their own filters. The key features of Filter Forge include a visual filter editor and a free online library of user-created filters to which anyone can contribute. Filter Forge can produce a wide range of textures and effects which include organic structures, metallic and rocky surfaces, distortions, abstract textures, repeating patterns, color corrections, and more. All filters are adjustable and editable, seamlessly tiled, resolution-independent, and support real-world HDRI lighting. Also, filters can automatically generate diffuse, specular, bump, and normal maps, which makes Filter Forge an essential tool for artists creating 3D models and environments, architectural visualization and high-end game content. With the Basic edition, users cannot create new and edit existing filters, as well as render normal, bump, diffuse, and other maps and use images larger that 3000x3000 pixels, open and save files in high-precision image formats (OpenEXR and PFM).
