Leaf MOS (or Aptus MOS, Mamiya MOS, etc.) is a raw image format used by some Mamiya/Leaf/Aptus digital cameras.

It is sometimes considered, along with Mamiya MEF, to be a member of the family of formats called Mamiya RAW.

Format

MOS is based on TIFF. The full-size image is in the first IFD, and uses Lossless JPEG compression.

MOS apparently uses a custom metadata format (stored in TIFF tag 34310), which uses the ASCII signature "PKTS".

Identification

The first (and only?) TIFF IFD uses Compression type 99, and contains tag 34310.
