What are the differences between cr2 and jpg file formats, and which one is better for professional photography?

The main differences between CR2 and JPG file formats are that CR2 is a raw file format that retains more image data and allows for greater editing flexibility, while JPG is a compressed file format that sacrifices some image quality for smaller file sizes.

For professional Photography, CR2 is generally considered better because it preserves more image data and provides more editing options, resulting in higher quality final images. However, JPG is more widely compatible and easier to share, making it more convenient for everyday use.
