About formats

MEF is the proprietary RAW image format used by Mamiya medium-format digital cameras, introduced with the Mamiya ZD in 2004 and continued through subsequent models including the DM series. MEF files capture the unprocessed output from Mamiya's large-area CCD sensors — typically 48x36mm or larger — at 16 bits per channel, preserving the full dynamic range and color depth of the medium-format sensor before any demosaicing, white balance, or tonal processing takes place. The format uses a TIFF-based container that stores the raw Bayer-pattern data alongside embedded JPEG previews and extensive EXIF metadata including Mamiya lens identification, shutter speed, aperture, and metering information. Mamiya (later reorganized as Mamiya Digital Imaging and eventually merged into Phase One's operations) has a legacy stretching back to 1940 in medium-format film photography, and the MEF format represents the digital continuation of that tradition. One advantage is the medium-format sensor's inherent imaging qualities: the larger sensor area captures more light per pixel, producing lower noise floors, smoother tonal gradations, and a shallower depth-of-field rendering that medium-format photographers value for portrait, fashion, and landscape work. RAW flexibility is another practical strength — MEF files processed in Adobe Lightroom, Capture One, or dcraw allow photographers to apply modern demosaicing and noise reduction algorithms to these sensors, often extracting noticeably better results than the camera's original processing offered.

PS is the standard extension for files written in PostScript, the page description language created by Adobe Systems and first shipped in 1984 with the Apple LaserWriter. A PostScript file is a complete program that describes the precise appearance of a page — text, vector graphics, curves, fills, and even embedded raster images — using a stack-based interpreted language with full programming constructs. When sent to a PostScript-compatible printer or interpreter (such as Ghostscript), the program executes and produces rendered output. PostScript introduced cubic Bezier curves as the standard representation for smooth outlines, a mathematical model that became the foundation for virtually all subsequent vector graphics and font technology including PDF, SVG, and OpenType. The language also serves as a font format: Type 1 PostScript fonts encode glyph outlines as PostScript programs with hinting instructions for sharp rendering at low resolutions, while Type 3 fonts use the full language to define arbitrarily complex glyphs. One advantage is device independence — a PostScript file produces identical output whether rendered on a 300 dpi desktop printer, a high-resolution imagesetter, or a software rasterizer, because it describes shapes mathematically rather than as pixel grids. The human-readable text format provides another practical strength: PS files can be inspected, debugged, and modified with any text editor, and they can be generated programmatically by any software without requiring specialized libraries. PostScript files are widely handled by Ghostscript, Adobe Acrobat, preview applications, and numerous publishing and graphics tools.
