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.
DCX (Multi-page PCX)
A legacy multi-page image format created for PC-based fax software.
DCX is a multi-page bitmap image format that essentially acts as a container for multiple PCX files. It was developed by ZSoft Corporation, the same company that created PC Paintrush and the PCX format. The primary purpose of DCX was to serve as the file format for early digital fax software, allowing a multi-page document to be stored in a single computer file. Technically, a DCX file begins with a header containing a list of offsets (pointers) to the individual PCX images stored within the file. Each 'page' is a fully valid PCX image with its own header and palette. The format relies on the simple RLE (Run-Length Encoding) compression inherited from PCX, which is efficient for simple black-and-white fax documents but poor for complex photographs.
A DCX file consists of a 4-byte signature (987654320) followed by an array of up to 1024 32-bit integer offsets. Each offset points to the start of a PCX image structure within the file. The list ends with a zero (null) terminator. Because it is wrappers around PCX, it shares all the characteristics of that format: support from 1-bit monochrome up to 24-bit RGB color. However, since it was primarily used for faxing, the vast majority of DCX files encountered today are 1-bit black and white.
DCX became popular in the early 1990s alongside the rise of fax modems and software like WinFax. It allowed users to scan or 'print' a document to a fax driver, which would save the pages as a linear .dcx file before transmission. As PDF became the dominant document format and email replaced faxing, DCX faded into obsolescence.
