CR3

CR3 is an advanced raw image file format developed by Canon for its digital cameras. It preserves high-quality, uncompressed images with extensive dynamic range and color depth, making it ideal for professional photographers. CR3 files offer superior editing flexibility, supporting advanced post-processing without loss of detail. This format is perfect for capturing stunning visuals in challenging lighting conditions.

FITS

FITS is a digital file format designed for the storage and transmission of scientific data, particularly in astronomy. Optimized for large datasets, it efficiently handles multi-dimensional arrays and metadata, making it indispensable for image and data analysis in telescopes and space missions. Its extensibility ensures compatibility across various platforms and software, securing its place as a vital tool in scientific research.
