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

  • Studio Photography: Legacy medium format shoots.

Advantages

  • Medium Format Look

Limitations

  • Slow Write Speed

About PSB Format

Photoshop Big

The 'Large Document Format' for managing gigapixel images.

Overview

PSB (Photoshop Big) is an extension of the PSD format designed to break the barriers of the 2GB file size limit and 30,000 pixel dimension limit of standard PSD files. It is structurally almost identical to PSD but uses 64-bit offsets inside the file to support massive files up to 4 Exabytes (theoretically) and 300,000 pixels in width/height.

Technical Details

Internally, a PSB file mirrors the block structure of a PSD (Header, Color Mode, Image Resources, Layer and Mask Info, Image Data). The key difference is the bit-width of length integers; PSB uses 8 bytes (64-bit) where PSD uses 4 bytes (32-bit) for describing file offsets and dimensions.

History

Introduced in Adobe Photoshop CS (v8.0) in 2003 to support the growing needs of astronomical imaging, billboard printing, and HDR photography.

Common Use Cases

  • Billboard Design: Designing a 50-foot wide banner at 300 DPI.
  • HDR Compositing: Multi-layer 32-bit float compositions often exceed 2GB quickly.

Advantages

  • Massive Scale
  • Full Feature Set

Limitations

  • Compatibility
  • Slow
