Pyramid TIFF
A multi-resolution TIFF optimized for deep zooming.
PTIF (Pyramid TIFF or Pyramidal TIFF) is a standard TIFF file that has been structured to contain multiple resolution levels of the same image (a 'pyramid'). This allows software to open immense images (e.g., gigapixel maps or medical scans) almost instantly by loading only the low-resolution tile suitable for the current zoom level, rather than decoding the entire massive file.
Inside the TIFF wrapper, the image is stored as a series of SubIFDs (Image File Directories). The main image is typically the highest resolution. Subsequent directories contain the image downscaled by powers of two (50%, 25%, 12.5%, etc.). Additionally, the image data is usually 'tiled' (broken into usually 256x256 blocks) rather than 'stripped'. This enables random access to specific regions.
Developed to handle the exploding size of satellite imagery and digital pathology slides.
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.
