Part 1: What is Canon CR2 Photo Format?

RAW is a collection of uncompressed image formats include CR2. It is a file type used by some popular Canon digital cameras, such as EOS400D, EOS450D, and more. To help you understand what Canon CR2 is, we will compare it with JPG below:

1. File extension. Canon CR2 files are ended with cr2, while JPG images are in jpg files. The former is far more than an image format but stores a lot of raw data. The latter is a standard image format readable by any image program on the market.

2. Quality. CR2 usually records 12 bits of color or 36 bits per location. JPG stores exactly 8 bits per color or 12 bits per location. Even you zoom out a CR2 image file, it won’t become blurry.

3. Compression. CR2 is a RAW format. It means that the image files contain extensive data and information captured by camera processors. JPG is a compressed image format instead. That makes CR2 better for adjustment and editing.

4. File size. Since CR2 is an uncompressed format and stores a lot of information, the file size is much larger than JPG.

Sometimes, you view the image stored in CR2 and JPG, but the latter may look better. That is due to Canon CR2 files storing the original image data. But JPG will become sharper and higher in contrast after compression. Therefore, CR2 is not suitable to print from your camera.
