What is a .cr2 file?

CR2 files are raw image files created by Canon digital cameras. They contain minimally processed data directly from the camera's sensor, preserving a high level of detail and dynamic range. This means CR2 files retain more information than standard JPEG images, allowing for greater flexibility in post-processing. Photographers often use CR2 files to adjust white balance, exposure, contrast, and other settings without significantly degrading the image quality. Because they are raw files, CR2 files are not directly viewable by most image viewers and require specialized software for processing and conversion. The format stores metadata about the image, including camera settings, date, and time. CR2 files are based on the TIFF file format and are typically larger in size than JPEG files due to the uncompressed or losslessly compressed nature of the data. They are essential for professional photographers who require maximum control over their images during editing.
