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.
This format is used to compress TIFF images when sending them via fax machines. This format helps reduce the data transmission time. Group 3 eliminates redundant data during compression in order to reduce file size. The standard 10:1 compression ratio may be increased to the user's preferences, but it can lead to a significant loss of image quality.
