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.
Compressed bitmap image that uses wavelet compression instead of the DCT compression used by standard .JPEG images; supports 16-bit color, alpha transparency, and lossless compression.
