RAW

The RAW image format captures unprocessed data from digital cameras, providing photographers with high-quality images and maximum editing flexibility. Unlike JPEGs, RAW files retain more detail and dynamic range, making them ideal for professional editing. Perfect for those who prioritize image fidelity, RAW files can be converted to JPEG or TIFF for easy sharing while maintaining the integrity of the original shot.

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.
