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 File Format
The advanced successor to JPEG that never quite took off on the web.
JPEG 2000 (JP2) is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard with a newly designed, wavelet-based method.
JP2 uses discrete wavelet transform (DWT) technology, which allows for higher compression ratios without the 'blocky' artifacts seen in standard JPEGs. It supports both lossy and lossless compression in a single architecture and allows for progressive decoding (quality or resolution).
Released in 2000 as a modern upgrade to JPEG. Despite its technical superiority, it failed to gain widespread web adoption due to patent concerns, complexity, and the 'good enough' nature of standard JPEG.
