What is CR2 file?

CR2 file stores raw image data captured with digital camera matrix developed by Ca non. It is the version 2 of the format. CR2 is a RAW, uncompressed image and therefore can be quite large. CR2 is a proprietary format that stores data in binary. CR2 must be ‘developed’ just like photo negative. Users can change image parameters, for example white balance or exposition. Canon cameras which first used CR2 format are the following:

  • 1D Mark II,
  • 20D,
  • 350D,
  • G9.

CR2 file has a header that contains EXIF data, information about the picture, camera, and image parameters. It also contains compressed preview image one-forth the size of base photo and small 160x120 pixels icon. CR2 file stores image in 12- or 14-bit color, while detailed structure of the file depends on th camera it was taken with.

CR2 is based on TIFF and replaced the CRW format in 2004. In 2018 Canon developed a newer version designated CR3, which is based on CIFF and is due to replace CR2 format. This year’s lineup of Canon reflex cameras offer option to save photos in RAW–CR2 format. Applications that support CR2 files must also support the Canon camera it was taken with. Developed and processed photo can be then saved in a more popular image format, for example JPEG, for easier distribution.

What else may cause problems?

There can be more reasons which determine that you are not able to open the CR2 file (apart from the lack of the proper application installed).

First - the CR2 file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the CR2 file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the CR2 file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the CR2 file has not been completed and it cannot be opened properly).
