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.
Common uses
- Medium-format studio and portrait photography
- Commercial product and fashion photography
- Landscape photography with high dynamic range
- Fine-art printing at large formats
About the MNG format
MNG — Multiple-image Network Graphics
MNG is the animated image sibling of PNG, designed to be a replacement for GIF animations. While technically superior (full color, gamma correction, more compression options), it never achieved widespread browser adoption and was largely superseded by APNG and WebP for animation.
Common uses
- Legacy MNG animation playback
- Converting MNG animations to APNG or GIF
- Archiving early web animations
- Advanced animation with embedded PNG frames
