Epson Raw File (.erf)

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.
