About the MEF format
RAW — Mamiya MEF RAW
MEF is Mamiya's proprietary RAW format used in medium-format Mamiya digital cameras and backs. Mamiya is known for its use in professional studio and portrait photography, and MEF files deliver the high dynamic range expected of medium-format imaging.

- Landscape photography with high dynamic range
- Fine-art printing at large formats
About the HDR format
HDR — Radiance RGBE High Dynamic Range

Common uses
