| Description | X3F is a raw image file format used by Sigma cameras. It is based on the TIFF format and uses a proprietary compression algorithm to store raw image data. X3F files can store both the raw image data and metadata such as exposure settings and camera information. |
| Technical details | The X3F format supports 12-bit or 14-bit color depth, depending on the camera model, and can produce high-quality images with low noise levels. X3F files are typically large in size due to the uncompressed raw image data, but they offer a high level of flexibility and control over image processing. X3F files can be opened and processed by various image editing software, but Sigma's proprietary software, Sigma Photo Pro, is recommended for best results. |
