About SRF Format

Sony Raw Format

The great-grandfather of Sony's ARW format.

Overview

SRF is the original raw format used by the very first Sony digital cameras, such as the Cyber-shot DSC-F828. It predates both SR2 and ARW. Like its successors, it contains uncompressed sensor data, but it uses older encryption and structure methods that are now largely obsolete.

Technical Details

SRF files are TIFF-based but heavily modified. They contain the raw data from the CCD sensors used in early 2000s Sony cameras.

History

Replaced by SR2, which was then replaced by ARW.

Common Use Cases

  • Archival: Restoring old photos.

Advantages

  • Raw Data

Limitations

  • Obsolete

About PBM Format

Portable Bitmap

The lowest common denominator of image formats.

Overview

PBM (Portable Bitmap) is the simplest format in the Netpbm suite, designed to represent monochrome (black and white) images. It uses a straightforward text-based (or simple binary) encoding where '1' represents black and '0' represents white (or vice versa depending on the viewer, though standard entails 1=black). It was designed to be easily emailed and processed by simple scripts.

Technical Details

There are two variants: P1 (ASCII) and P4 (Binary). ASCII P1: The file is human-readable text. A grid of 0s and 1s defines the image. Binary P4: The bits are packed into bytes for efficiency. The header simply states the magic number (P1 or P4) and the dimensions. There is no compression, no index, no palette.

History

Invented by Jef Poskanzer in the 1980s as a way to send bitmaps via email properly. It became the foundation of the 'pbmplus' (later 'netpbm') toolkit, which provided a standard way to convert between dozens of incompatible 80s file formats.

Common Use Cases

  • OCR Interchange: Feeding scanned pages into OCR software.
  • Hardware Control: Creating bitmaps for thermal printers or LCD screens.

Advantages

  • Simplicity
  • Robustness

Limitations

  • No Color
  • Inefficient
