The ERF, which refers to Epson Raw File, is a proprietary format used by Epson digital cameras to store uncompressed image data, capturing all sensor details. This format enables high-quality images and extensive post-processing flexibility. ERF files can be edited with specialized software, and some Epson cameras include a utility for basic adjustments. Although ERF files are large and require more storage and processing power, they are preferred by professional photographers for their superior quality and editing capabilities.
The G4 file extension, standing for CCITT Group 4 Fax Image, is a specialized format used primarily for storing black-and-white facsimile (fax) images. Its origins trace back to the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as the ITU-T, which developed the Group 4 standard in the 1980s to improve fax transmission efficiency over digital networks. This format employs a high compression ratio to reduce file size while maintaining image quality, making it ideal for archiving documents and transmitting faxes in professional and business environments.
