Source Format

Sony Raw Image

image/x-sony-arw

ARW (Alpha Raw) is Sony's proprietary raw image format used by Sony Alpha mirrorless and DSLR cameras. Based on the TIFF specification, it stores unprocessed 12-bit or 14-bit sensor data with complete metadata. ARW files can be either uncompressed or use Sony's lossy or lossless compressed raw encoding.

Advantages

  • Preserves full unprocessed sensor data for maximum post-processing latitude
  • Supports both compressed and uncompressed raw storage options
  • Well-supported by major photo editing applications including Lightroom and Capture One

Limitations

  • Proprietary format with no publicly available specification
  • Large file sizes, especially in uncompressed mode
  • Requires raw-capable software for viewing and editing

Common Uses

  • Professional photography with Sony Alpha series cameras
  • Raw photo editing and non-destructive development
  • High-quality archival of photographic captures

Target Format

PPM Image

image/x-portable-pixmap

PPM (Portable Pixmap Format) is a simple, uncompressed color image format belonging to the Netpbm family. It stores RGB pixel data in a straightforward human-readable ASCII or more compact binary format with a minimal header. PPM is valued for its extreme simplicity, making it easy to generate and parse programmatically.

Advantages

  • Extremely simple format that is easy to read and write programmatically
  • No compression means no quality loss whatsoever
  • Portable across different platforms with no library dependencies

Limitations

  • Very large file sizes due to no compression
  • No support for alpha transparency or metadata
  • Not practical for storage or distribution of images

Common Uses

  • Intermediate format in image processing pipelines and scripts
  • Teaching and learning image processing fundamentals
  • Simple data exchange between command-line image tools
