Do you frequently use CR2 files? If so, you would be aware of the host of benefits they offer, which is why they are widely used. But you might also note that CR2 files often get damaged.

In case you are wondering how to repair CR2 files, we have got some very useful tips that can indeed help your cause. But before we delve deep into the topic, let us begin by understanding what CR2 files are.

What Does a CR2 File Mean?

Putting it in simple language, CR2 is a RAW digital photography format that Canon developed. These files are based on the TIFF file specification. The format stores lossless details from the camera sensor without processing the image, which means that they are usually of high image quality.

However, CR2 is a completely unprocessed file. It is sent directly from the sensor without data loss or quality loss, so the file is large and contains camera information, lens information, bracketing information, white balance, and other settings. For example, compared to other image file formats (such as Jpeg) that record up to about 8 bits of RGB, CR2 files record up to 14 bits of RGB. This is different from the corresponding jpeg file, which is called the original file. Since their 350D, 20D, and 1D MarkII camera models, Canon's been using this format.
