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.

PICT is a metafile graphics format created by Apple Computer as the native graphics format for the Macintosh, debuting alongside the original Mac in January 1984 and remaining central to Mac OS graphics until the transition to Mac OS X. PICT files record a series of QuickDraw operation codes (opcodes) that reproduce the image when replayed through the QuickDraw graphics engine: operations for drawing lines, arcs, rectangles, rounded rectangles, ovals, polygons, regions, text strings, and pixel maps (bitmaps). This opcode-based approach means PICT files are not simply pixel grids but rather programmatic descriptions of how to draw the image, combining resolution-independent vector elements with pixel data in a unified stream. The PICT 2 revision, introduced with the Macintosh II and Color QuickDraw in 1987, extended the format to handle 24-bit color, multiple pixel depths, extended color spaces, and embedded JPEG and PackBits compressed data. PICT was integral to the Macintosh user experience: system clipboard operations (Copy/Paste), screen capture, printing, and inter-application data exchange all used PICT as the common visual representation. One advantage is historical comprehensiveness: PICT files from the classic Mac era capture both the visual output and the drawing methodology of Mac applications, preserving not just the image but the QuickDraw operations that produced it — valuable for understanding the visual computing paradigm of early Macintosh software. The format's extensive use in desktop publishing during the DTP revolution of the late 1980s provides another dimension of historical importance. PICT files are readable by macOS Preview, ImageMagick, XnView, LibreOffice, and GraphicConverter.
