Targa ICB
A legacy extension for Targa images created by Truevision ICB boards.
The ICB file extension is functionally identical to the standard TGA (Truevision Targa) format. It was specifically used to denote images created by or for the Truevision Image Capture Board (ICB). Like standard TGA files, it supports simpler raster data with optional RLE compression and alpha transparency.
An ICB file respects the TGA 2.0 specification. It contains a header defining image dimensions and pixel depth, followed by pixel data. The pixel data can be uncompressed or RLE-compressed. It supports bit depths of 8, 16, 24, and 32 bits. In 32-bit mode, 8 bits are dedicated to an alpha channel, which was a pioneering feature for video overlay graphics.
Truevision (now part of Avid) introduced the Targa video boards for IBM PC-compatibles in the 1980s. To distinguish files created by different hardware models, they used specific extensions: .tga (generic), .icb (Image Capture Board), .vda (Video Display Adapter), and .vst (Video Super TarGA). Modern software treats them all as standard TGA files.
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.
