Convert DNG to G3

The Digital Negative (DNG) file extension, developed by Adobe Systems and introduced in 2004, is an open, lossless raw image format designed for digital photography. DNG aims to provide a standardized format for raw files, ensuring compatibility across various software and hardware platforms. It is based on the TIFF/EP standard and incorporates extensive metadata, making it suitable for long-term archival purposes. DNG files are widely supported by numerous camera manufacturers and software applications, facilitating efficient storage, sharing, and editing of high-quality images.

The G3 file extension refers to the CCITT Group 3 Fax Image, a standardized format developed by the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as ITU-T. This format was created to efficiently compress black-and-white fax documents for transmission over telephone lines. It employs a method called Modified Huffman Coding for data compression, enabling reduced transmission time and bandwidth usage. G3 was widely adopted in the 1980s and 1990s as the primary standard for fax transmissions, ensuring compatibility across different fax machines and systems.
