The DNG (Digital Negative) file format is a proprietary, publicly available lossless raw image format developed by Adobe. It is intended to be a universal raw image format for digital cameras, aiming to standardize the way raw image data is stored. Unlike JPEG, which is a processed and compressed image format, DNG files contain minimally processed data directly from the camera's sensor. This allows photographers to have greater control over the final image during post-processing, adjusting parameters like white balance, exposure, and contrast without permanently altering the original data. DNG files often include metadata such as camera settings, date and time, and GPS coordinates. The format is designed to be future-proof, ensuring that raw image data remains accessible even as camera technology evolves. While many camera manufacturers have their own proprietary raw formats, DNG offers a standardized alternative that promotes interoperability and long-term archival of digital photographs. It is often used by photographers who want to preserve the maximum amount of image data and maintain flexibility in their workflow.
