- Description
- The X3F file format, also known as the SIGMA X3F Camera RAW File, is a proprietary image format developed by Sigma Corporation for storing raw image data captured by Sigma cameras equipped with the Foveon X3 sensor. Unlike standard JPEGs or TIFFs, X3F files contain unprocessed data from the camera's sensor, offering photographers greater flexibility in image editing.
- Image stored in the JPEG XR format, which was originally developed by Microsoft for Windows Media software; supports deep color images with 48-bit RGB; used for high-resolution professional image editing; also supports lossless and lossy compression.
