What is an X3F file?
An X3F file is a raw image format used by Sigma digital cameras (especially those with Foveon X3 sensors, e.g., SD9, SD14, SD1, fp). It stores unprocessed sensor data — capturing full RGB values at each pixel (unlike Bayer sensors) — along with JPEG previews, metadata, and often a thumbnail. X3F enables high color fidelity and detail, unique to Foveon technology.
