What Is a CR2 File?

What is a CR2 file? It is a standard file extension for all pictures you take with a Canon camera. The format’s full name is Canon Raw 2. Many photographers are actively using CR2 files since they save all the digital info from the original shot. This format is created on the basis of the TIFF file, which is known for delivering qualitative pictures as well.

CR2 file is a raster one, meaning that the info about a picture is saved in the form of the pixel grid. One pixel stands for a separate color. Since .cr2 is a RAW file format, it doesn’t compress any info from a picture and leaves the widest possible space for picture post-production. The information is stored so the actual picture is presented as a gray-scale encoded color filter array. To get an RGB image, the array must be deconvoluted. Moreover, CR2 files include metadata about a picture, such as a lens and a camera used, WB settings, etc.

The size of an unprocessed CR2 file is rather large. The file will consume plenty of system resources when you are editing it. That’s why, if you take shots for your Instagram profile or for a family album, which doesn’t require printing pictures in a very big size, the .cr2 file extension won’t be suitable for you. In this case, saving shots in JPEG will be the most optimal option.

But if you are a professional shooter, who takes pictures for commercial purposes, the CR2 file format will be an ideal variant. This format will come in handy in cases when the pictures contain a lot of white and light details. It allows adjusting the picture up to five stops of light and fixing the white balance.

Pros+
  • High resolution
  • Almost all the details are preserved
  • Possibility to adjust pictures up to five stops of light
  • Perfectly suitable for large pictures, e.g. billboards
Cons-
  • One of the biggest formats for managing
  • To read .cr2 files, you need a specific program or a plug-in depending on the Canon camera model
  • Uploading .cr2 files to online picture editors isn’t simple
