About MEF Format

Mamiya RAW

Raw format for the Mamiya ZD and digital backs.

Overview

MEF is the raw image format used by Mamiya digital cameras, most notably the Mamiya ZD medium format DSLR. Before Mamiya was acquired by Phase One, they produced their own digital backs and integrated cameras.

Technical Details

MEF files contain high-resolution medium format sensor data (typically 22MP in the ZD era). They are TIFF-based and store 14-bit or 16-bit data.

History

Mamiya was a titan of film medium format. Their transition to digital was rocky, and the MEF format is a relic of that transition period before Phase One took over the ecosystem.

Common Use Cases

About QOI Format

Quite OK Image Format

Lossless compression that is incredibly fast.

Overview

QOI (Quite OK Image Format) is a modern lossless image format created by Dominic Szablewski in 2021. It was designed to be a simpler, faster alternative to PNG, prioritizing encoding and decoding speed over maximum compression ratio.

Technical Details

The QOI specification fits on a single page of paper. It achieves compression ratios similar to PNG but encodes 20x-50x faster and decodes 3x-4x faster. It uses a simple streaming algorithm with a running array of previously seen colors.

History

Released in 2021 as a reaction to the complexity of formats like PNG and the slowness of their reference implementations. It quickly gained viral popularity in the developer community.
