CR2 to FITS: what carries over and what does not

CR2 files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to FITS bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after.

"I regularly process hundreds of RAW files from multiple shoots. reaConverter's batch processing capabilities have transformed my workflow, allowing me to convert CR2 and NEF files to high-quality 16-bit TIFFs while preserving all metadata and color profiles. The ability to apply consistent sharpening and noise reduction during conversion saves me approximately 2 hours per project in post-production."

CR2 to FITS Conversion: FAQ

What are CR2 files?

CR2 is the RAW format used by Canon cameras. Also known as "digital negatives", RAW images are often preferred by photographers because they can be highly customized during the digital post-processing and they retain a large amount of image details. The disadvantage of using this format is its enormous size, which makes it difficult to store or send by email. In addition, CR2s are not compatible with many image viewing programs and are not accepted by image sharing websites.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
