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.
Microsoft Icon
The standard format for icons on Microsoft Windows and the web (favicons).
The ICO format is a container for one or more images at multiple sizes and color depths. It allows a single file to store appropriate icons for different display contexts (e.g., 16x16 for menus, 256x256 for desktop). It supports transparency and, in modern versions, PNG compression.
ICO files contain a header followed by an icon directory that lists each image entry. Each entry can use either BMP (uncompressed) or PNG compression. The format supports 1, 4, 8, 16, 24, and 32-bit color depths with optional alpha channels.
Introduced with Microsoft Windows 1.0. It became the standard for website favicons with the release of Internet Explorer 5.
