About SR2 Format

Sony RAW 2

The predecessor to the modern ARW format.

Overview

SR2 is an older raw image format used by early Sony digital cameras, particularly the Cyber-shot R1 and early DSLRs before the Alpha branding fully took over with the ARW format. It contains raw sensor data, allowing for the same kind of editing flexibility as modern raw files, but from older sensor technology.

Technical Details

SR2 is a TIFF-based format. It typically stores 12-bit data. The encryption used in SR2 files was a point of contention in the early days of open-source raw decoding.

History

Sony used SRF, then SR2, and finally settled on ARW. SR2 represents the middle child of this evolution.

Common Use Cases

  • Archival: Old Sony photos.

Advantages

  • Raw Data

Limitations

  • Obsolete

About PGM Format

Portable Gray Map

The standard uncompressed grayscale format.

Overview

PGM (Portable Gray Map) is the grayscale member of the Netpbm format family. It sits between PBM (1-bit black and white) and PPM (full color). It is designed to store grayscale images where each pixel has a value ranging from black to white, with typical depths of 8-bit (0-255) or 16-bit (0-65535).

Technical Details

Like other Netpbm formats, PGM has two sub-formats: P2 (ASCII) and P5 (Binary). The header defines the dimensions and the maximum gray value (Maxval). In P2, pixel values are written as plain text numbers separated by spaces. In P5, they are raw bytes. It is strictly a single-channel format.

History

Created by Jef Poskanzer in the late 80s to handle scanned photos that were better than 1-bit bitmaps but didn't need full color. It became a staple in computer vision research and Unix tools.

Common Use Cases

  • Computer Vision: Input for facial recognition or edge detection algorithms.
  • Heightmaps: Storing terrain elevation data for game engines.

Advantages

  • Simplicity
  • Clarity

Limitations

  • No Color
  • Inefficient
