Why convert CR2 to HDR?

The main issue with CR2 is lack of browser support. Converting to HDR fixes this by providing perfect pixel preservation with smaller files. Converting CR2 RAW images to HDR applies essential post-processing: white balance, demosaicing, and tone mapping. The result is a standard image ready for printing or further editing in any software.
