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.
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.
