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.
An AZW3 file is an eBook created in the Kindle Format 8 (KF8), Amazon's successor to the .AZW format. It supports newer features such as HTML5 and CSS3 support as well as many other formatting capabilities. AZW3 files often include DRM protection and are used as the download format for many Amazon eBooks.
