Phase One IIQ
Intelligent Image Quality for high-end medium format photography.
IIQ (Intelligent Image Quality) is the proprietary raw image format developed by Phase One for their high-end medium format cameras. Known for storing massive amounts of data from sensors exceeding 100 megapixels, IIQ files are designed to preserve the utmost color fidelity and dynamic range, catering to professional commercial and landscape photographers.
IIQ files are essentially specialized TIFF containers. They come in two primary compression variants: - **IIQ L (Large)**: A comprehensive lossless format. It keeps 100% of the sensor data but results in very large files. - **IIQ S (Smart)**: An intelligent near-lossless compression. It reduces file size significantly (often by 30-50%) by discarding data that is mathematically redundant or invisible to the human eye, without degrading the editability of the raw file.
Phase One introduced IIQ alongside their digital backs to handle the enormous data throughput of medium format sensors. It evolved in tandem with their Capture One software, which is widely regarded as the industry standard for tethered shooting and raw color grading.
JPEG 2000 Compound Image
JPEG 2000 for multi-layer documents.
JPM (JPEG 2000 Part 6) is a compound image file format. It is designed for storing document images that contain a mix of text and graphics, using a Mixed Raster Content (MRC) model. It allows for different compression methods to be applied to different 'layers' of the image (e.g., sharp edges for text, smooth gradients for photos).
JPM splits an image into multiple layers (e.g., background, foreground mask, foreground color). Each layer can be compressed differently (e.g., JBIG2 for text mask, JPEG 2000 for background photos), optimizing both quality and file size for scanned documents. This is significantly more efficient than compressing an entire scanned page as a single JPEG 2000 image.
Part of the JPEG 2000 standard (ISO/IEC 15444-6), specifically targeting the document archival market.
