- 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.
- Created by JBIG (Joint Bi-level Image Experts Group), JBG is a lossless file format that contains both colored and monochrome images. Commonly used to compress fax images, and it has better compression than G3 and G4 compression codecs.
