Mamiya RAW
Raw format for the Mamiya ZD and digital backs.
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.
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.
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.
Targa ICB
A legacy extension for Targa images created by Truevision ICB boards.
The ICB file extension is functionally identical to the standard TGA (Truevision Targa) format. It was specifically used to denote images created by or for the Truevision Image Capture Board (ICB). Like standard TGA files, it supports simpler raster data with optional RLE compression and alpha transparency.
An ICB file respects the TGA 2.0 specification. It contains a header defining image dimensions and pixel depth, followed by pixel data. The pixel data can be uncompressed or RLE-compressed. It supports bit depths of 8, 16, 24, and 32 bits. In 32-bit mode, 8 bits are dedicated to an alpha channel, which was a pioneering feature for video overlay graphics.
Truevision (now part of Avid) introduced the Targa video boards for IBM PC-compatibles in the 1980s. To distinguish files created by different hardware models, they used specific extensions: .tga (generic), .icb (Image Capture Board), .vda (Video Display Adapter), and .vst (Video Super TarGA). Modern software treats them all as standard TGA files.
