- 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.
- Compressed bitmap image that uses wavelet compression instead of the DCT compression used by standard .JPEG images; supports 16-bit color, alpha transparency, and lossless compression.
