Understanding PBM and CR2 Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

PBM Image

image/x-portable-bitmap

PBM (Portable Bitmap Format) is the simplest format in the Netpbm family, storing binary (black and white) images where each pixel is either 0 or 1. It uses a minimal plain-text header followed by pixel data in ASCII or binary encoding. PBM is commonly used for monochrome images in programming education and simple image processing tasks.

Advantages

  • Simplest possible image format, trivial to implement from scratch
  • Human-readable ASCII mode allows manual creation and inspection
  • No external dependencies or complex decoding required

Limitations

  • Limited to strictly black and white (1-bit) images with no grayscale
  • No compression support leads to inefficient storage
  • Not suitable for any practical image storage or distribution

Common Uses

  • Programming education and introductory image processing exercises
  • Binary mask representation in image processing pipelines
  • Simple pattern and bitmap generation in scripts

Target Format

Canon Raw Image

image/x-canon-cr2

CR2 (Canon Raw version 2) is Canon's proprietary raw image format used by Canon DSLR and mirrorless cameras. It stores unprocessed sensor data with full bit depth, white balance, and exposure settings as metadata rather than baked-in adjustments. CR2 files provide maximum flexibility for post-processing, preserving all the data captured by the camera sensor.

Advantages

  • Preserves complete unprocessed sensor data for maximum editing flexibility
  • Widely supported by major photo editing software including Lightroom and Capture One
  • Contains extensive EXIF metadata including camera settings and lens information

Limitations

  • Proprietary format controlled by Canon with no public specification
  • Large file sizes, typically 20-30 MB per image for modern cameras
  • Requires specialized raw processing software to view and edit

Common Uses

  • Professional and enthusiast photography with Canon cameras
  • Non-destructive photo editing and raw development
  • High-quality image archival preserving maximum sensor data
