X3F to CG4 Conversion: FAQ

What are X3F files?

X3F is a RAW image format used by Sigma cameras. This well-known Japanese brand is responsible for producing high-quality lenses, flashes, cameras and other photographic accessories. The X3F format is enhanced by the use of Foveon technology, which allows the camera's sensor to capture colors with an increased richness of detail. As opposed to JPG, X3F images allow the photographer to capture a wider variety of image information, which he will be able to select during post-processing.
