Convert CR2 to ARW

Understanding CR2 and ARW file formats

The CR2 file format, or Canon Raw Version 2, is a raw image format used by Canon digital cameras. It stores uncompressed image data directly from the camera's sensor, allowing photographers to have greater control over editing and post-processing. On the other hand, the ARW file format is a raw image format used by Sony digital cameras. Like CR2, ARW files contain unprocessed data from the camera sensor, providing high-quality images that can be extensively edited.

Why convert CR2 to ARW?

Converting CR2 to ARW might be necessary if you are working within a Sony-centric workflow or using software that better supports ARW files. However, it's important to note that converting between raw formats can sometimes lead to data loss or quality degradation, so it's generally recommended to keep the original raw files whenever possible.

Best software for CR2 to ARW conversion

While direct conversion from CR2 to ARW is not commonly supported due to the proprietary nature of raw formats, you can use software to convert CR2 files to a more universal format like DNG, and then to ARW if necessary. Here are some recommended tools:

• Adobe Lightroom: Import your CR2 files and use File → Export to convert them to DNG, which can then be converted to ARW using specialized software.
• Adobe DNG Converter: A free tool from Adobe that can convert CR2 files to DNG format.
• RawTherapee: An open-source raw image processing software that supports a wide range of raw formats, including CR2 and ARW.

Steps to convert CR2 to ARW

1. Open your CR2 file in Adobe Lightroom or another compatible software.
2. Use the File → Export option to convert the CR2 file to DNG format.
3. Use a specialized tool or script to convert the DNG file to ARW, if necessary.

Remember, it's always best to keep a backup of your original CR2 files before attempting any conversion.
