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 JAR format
JAR — Java Archive
A JAR file is a ZIP archive that packages compiled Java classes, resources and a manifest into one distributable file. Because the container is plain ZIP, a JAR can be opened, repacked or converted with any archive tool — the only thing that makes it a JAR is the META-INF/MANIFEST.MF entry.
Common uses
- Packaging a Java library or application for distribution
- Inspecting or extracting the contents of a compiled Java program
- Converting a ZIP of class files into a loadable JAR
- Repacking a Minecraft mod or plugin archive
