Mamiya Electronic Format (.mef)
The Mamiya Electronic Format (MEF) is a raw image file format used by Mamiya digital cameras to store unprocessed and uncompressed image data directly from the camera sensor. Introduced in the mid-2000s, MEF files maintain the original scene's dynamic range and quality, allowing professional photographers extensive post-processing control. These files are typically large due to their uncompressed nature and include vital metadata such as exposure settings and white balance. MEF files are commonly edited using specialized software like Adobe Photoshop and Lightroom.
