What is a MOS file?
The MOS format is a proprietary raw image container created by Leaf Imaging (now Phase One) for use with their Credo and Aptus series digital backs. It captures unprocessed data directly from the CCD or CMOS sensor, storing it in a TIFF-based structure that retains high dynamic range and original color depth (16-bit). The file acts as a digital negative, preserving all metadata including white balance, exposure settings, and sensor calibration data, necessitating demosaicing algorithms during post-processing to render a viewable image.
How to open a MOS file
MOS files require specialized raw processing software due to their proprietary encoding. Phase One Capture One is the primary software for full support, given the manufacturer lineage. Adobe products (Photoshop, Lightroom) support MOS via the Adobe Camera Raw plugin. For free alternatives, users can utilize RawTherapee or Darktable, which include the necessary decoding libraries (LibRaw) to interpret the sensor data on Windows, macOS, and Linux.
