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.
Photoshop Document
The industry standard for digital image editing.
PSD (Photoshop Document) is the proprietary file format of Adobe Photoshop. It is the de facto standard in the digital art, photography, and graphic design industries. Unlike final output formats (JPG, PNG), a PSD is a working file that preserves the editor's state: independent layers, editable text, masks, blend modes, filters, and paths.
A PSD file is divided into five major parts: File Header, Color Mode Data, Image Resources (metadata like paths, guides), Layer and Mask Information (the bulk of the data), and Image Data (a flattened backward-compatible preview). This structure allows Photoshop to save complex non-destructive editing states.
Created by Thomas Knoll in 1988 for the original version of Photoshop. It has evolved with every version of the software, adding support for new features (vectors in v6, smart objects in CS2) while maintaining remarkable backward compatibility.
