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.
WebP Image (WEP) is an image file format developed by Google in 2010. It is based on the VP8 video format and is used to create smaller, higher quality, and lossy compressed images. It is supported by most major web browsers and is commonly used for web graphics.
