Questions & Answers
CR3 images: Frequently Asked Questions
What are CR3 files?
CR3 is a digital photo file format that is used by Canon cameras. It is the successor to the CR2 format and was introduced in 2018 with the release of the Canon EOS M50 camera. CR3 files contain raw image data captured by the camera's sensor, which allows for greater flexibility in post-processing. The CR3 format also supports new features such as Dual Pixel RAW, which allows for adjustments to be made to the focus point after the photo has been taken. However, because it is a proprietary format, not all software applications may be able to open or edit CR3 files without additional plugins or updates.
