Format Overview & Applications
An editor can circulate a CR2 proof as a document while asking the photographer to retain the original for crop or exposure changes.
Technical Specifications & Codec Breakdown
The CR2 is developed through LibRaw’s AHD demosaic with camera white balance and camera-matrix color, then oriented and emitted as 8-bit sRGB.
OS & Browser Compatibility
Canon Digital Photo Professional and raw editors can adjust the CR2; a PDF proof can be circulated to editors who need to mark up the selected appearance.
Useful info
Choose the final crop and white balance in the raw editor first; the PDF conversion does not retain CR2 crop or development controls.

Can this page be used to approve the crop?
