DNG

The DNG (Digital Negative) format is a royalty-free file format for raw images developed by Adobe. It serves as a universal standard that preserves the integrity of original raw images while allowing for easy editing and archiving. By supporting DNG, photographers ensure compatibility with a wide range of software and equipment, enhancing workflow efficiency and image preservation.

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.
