Convert DCR to G3

The DCR (Digital Camera Raw) file extension is used by Kodak digital cameras to store uncompressed, lossless image data exactly as captured by the camera's sensor. This format retains more detail and allows for greater post-processing flexibility compared to compressed formats like JPEG. DCR files contain metadata such as camera settings and image dimensions. Historically, Kodak introduced this format to provide photographers with high-quality images for editing and archival purposes.

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.
