About formats

IIQ (Intelligent Image Quality) is the proprietary RAW format developed by Phase One, a Danish manufacturer of medium-format digital camera systems and backs, introduced in 2008 with the P65+ digital back. IIQ files capture the unprocessed readout from Phase One's large-area CCD and CMOS sensors — ranging from 40 to 151 megapixels in current systems — at 16 bits per channel, preserving the full dynamic range, color depth, and spatial resolution of the sensor. The format comes in two variants: IIQ Large (IIQ L), which uses lossless compression for zero-quality-loss archival, and IIQ Small (IIQ S), which applies visually lossless compression to reduce file sizes by approximately 40-60% with negligible quality impact. Phase One's sensor calibration data, including per-pixel defect maps, fixed-pattern noise profiles, and factory color calibration, is embedded in the IIQ file, enabling precise correction during RAW development. One advantage is sheer resolving power and tonal depth: IIQ files from Phase One's flagship systems deliver the highest pixel counts and widest dynamic range available in commercial photography, making them the standard format for museum digitization, fine art reproduction, aerial surveying, and commercial advertising where maximum detail is non-negotiable. Tight integration with Capture One is another key strength — Phase One develops both the camera hardware and the RAW processing software, ensuring that IIQ files receive optimized demosaicing, color rendering, and lens correction tuned to each specific camera-lens combination.
Developer: Phase One
Initial release: 2008
MAP is an internal raster image format used by ImageMagick, the open-source image processing suite first released by John Cristy at DuPont on August 1, 1990. MAP files store indexed-color (color-mapped) images in ImageMagick's native representation: a color palette (the map) followed by pixel data where each pixel is an index into that palette rather than a direct RGB value. The format provides a compact representation for images with a limited number of distinct colors — each pixel requires only enough bits to index the palette (typically 8 bits for up to 256 colors), compared to the 24 or 32 bits per pixel required by full-color formats. MAP serves primarily as an intermediate format within ImageMagick's processing pipeline, useful when performing operations that benefit from or require palettized representation: color quantization (reducing an image to a specific number of colors), palette manipulation, GIF preparation, and indexed-color analysis. The format is invoked through ImageMagick's standard I/O syntax and can be piped between processing stages without disk overhead. One advantage is direct access to ImageMagick's color quantization and palette management capabilities: MAP format output makes the palette structure explicit and manipulable, enabling workflows where specific palette operations (reordering, remapping, merging) need to be performed between processing steps. The format's integration into the ImageMagick processing ecosystem is another practical strength — any of ImageMagick's extensive image manipulation operations can consume or produce MAP format data, making it a natural intermediate for color-reduction pipelines that ultimately target GIF, PNG with palette, or other indexed-color formats.
