About CR2 Format

Canon RAW 2

The standard raw format for Canon DSLRs from 2004 to 2018.

Overview

CR2 (Canon Raw version 2) is the proprietary raw image format used by Canon EOS digital SLR cameras from the mid-2000s until the introduction of the CR3 format in 2018. If you shot with a Canon 5D Mark II, 7D, or Rebel T3i, you have thousands of these files. Like all raw formats, a CR2 file contains the unprocessed data from the image sensor. It is not an image yet; it is a dataset of light intensity values that must be 'demosaiced' by software to create a viewable picture. This allows you to change the white balance, recover highlights, and pull detail out of shadows long after the photo was taken.

Technical Details

CR2 is based on the TIFF file structure. It uses lossless compression to store the sensor data, which is typically 12-bit or 14-bit depending on the camera model. The file contains the raw image data, a full-size JPEG preview (for reviewing on the camera screen), and extensive 'MakerNotes' metadata that records every camera setting, from the lens used to the focus point selected.

History

CR2 replaced the older CRW format in 2004 with the release of the EOS 20D. It remained the standard for 14 years, making it one of the most widely supported and understood raw formats in history. It was eventually succeeded by CR3, which offers better compression.

About QOI Format

Quite OK Image Format

Lossless compression that is incredibly fast.

Overview

QOI (Quite OK Image Format) is a modern lossless image format created by Dominic Szablewski in 2021. It was designed to be a simpler, faster alternative to PNG, prioritizing encoding and decoding speed over maximum compression ratio.

Technical Details

The QOI specification fits on a single page of paper. It achieves compression ratios similar to PNG but encodes 20x-50x faster and decodes 3x-4x faster. It uses a simple streaming algorithm with a running array of previously seen colors.

History

Released in 2021 as a reaction to the complexity of formats like PNG and the slowness of their reference implementations. It quickly gained viral popularity in the developer community.

Common Use Cases

  • Game Development: Fast asset loading.
  • Embedded Systems: Devices with limited CPU power.

Advantages

  • Speed
  • Simplicity

Limitations

  • Browser Support
  • Compression
