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 PNM Format

Portable Any Map

A super-class extension for the PBM, PGM, and PPM formats.

Overview

PNM (Portable Any Map) is not a distinct file format itself but rather a collective name (and file extension) used to handle files that could be any of the specialized Netpbm formats: PBM (Bitmap), PGM (Graymap), or PPM (Pixmap). A file ending in `.pnm` allows a program to implement a single reader that automatically detects the internal format ('P1' through 'P6') and handles it accordingly.

Technical Details

A `.pnm` file is simply a PBM, PGM, or PPM file renamed. The header magic number (e.g., `P6`) determines the actual content. This abstraction simplifies command-line pipelines, allowing users to pipe `image.pnm` without worrying if the image is black-and-white or full color.

History

Part of the Netpbm project philosophy to create a unified library for handling raster graphics. It simplifies naming conventions for software that can output any of the subtypes.

Common Use Cases

  • General Output: A scanning script that saves to `.pnm` regardless of whether the user selected Color or Grayscale mode.
  • Data Pipes: Unix pipes often use the generic `pnm` terminology.

Advantages

  • Convenience

Limitations

  • Ambiguity
  • No Compression
