- Description
- The CAT file type, associated with Photomatix, is a proprietary file format used by Photomatix software, which is a popular tool for creating and editing high dynamic range (HDR) images. This file format is specifically designed to store data and settings used during the HDR photo editing process, such as tone mapping and exposure blending options. By saving a project as a CAT file, users can preserve their editing workflow, allowing for easy revisiting and adjustment of HDR images at any point in the future. This makes the CAT file format an essential asset for photographers and digital artists who frequently work with HDR imaging in Photomatix.
- Image file saved by the Krita painting program. A Krita file is a zip archive holding the full layer stack: each layer's pixel data as compressed tiles, its name, position, opacity, blending mode and visibility, plus a merged preview of the whole image.
