Sigma X3F

Sigma X3F is a raw image file format used by Sigma cameras. It captures unprocessed data from the camera's sensor, preserving maximum detail and color information. This allows photographers to extensively edit and adjust the image while maintaining high quality. Think of it as a digital negative that provides more flexibility and control over the final look of your photos compared to standard JPEGs or other compressed formats. To work with X3F files, specialized software like Sigma Photo Pro is typically needed.
