CR2
CR2 is a proprietary raw image file format used by Canon digital cameras. It retains unprocessed image data, allowing for extensive editing and adjustments in post-processing. Leveraging this format enhances image quality by preserving dynamic range and detail, making it a favorite among professional photographers. Discover the potential of CR2 for capturing stunning visuals with precision.
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.
