How to Open an EOS File

Canon's EOS, or Electro-Optical Systems, for Digital-SLR cameras captures still images in Canon's proprietary CR2 format. Known also as RAW images, these files contain all the metadata associated with the pictures, like the white balance and color temperature.
However, you need image processing software to view or edit them. Fortunately, Canon provides EOS camera users with free software called Digital Photo Professional, or DPP, allowing you to view, correct and even convert your RAW images to other formats. This software came with your camera, but it is recommended you upgrade to the latest version of DPP before you begin.
