The MEF file format stands for Mamiya RAW Image and is used to store images captured by Mamiya digital cameras, a brand known for its medium format cameras and lenses. Similar to other RAW image formats, MEF files contain all the data captured by the camera's sensor, without any in-camera processing or compression. This allows photographers to have greater control over photo editing, enabling them to adjust exposure, white balance, and other parameters without loss of image quality.
Color bitmap image format created by Silicon Graphics (SGI); generic format used for saving RGB color images on SGI workstations; recognized by various image viewing programs.
