What is a ERF file?

ERF is a proprietary RAW image format developed by Epson for its line of digital cameras, such as the Epson R-D1. It stores unprocessed sensor data, giving photographers full control over image adjustments like exposure, white balance, and contrast.

ERF files are based on the TIFF format and contain metadata specific to Epson’s camera system. While not widely used today, the format is valued by enthusiasts and collectors of Epson rangefinder-style cameras.

How to open ERF files

ERF files can be opened using Epson’s own software or RAW-capable editors such as Adobe Lightroom and Photoshop. Third-party tools like RawTherapee or IrfanView (with plugins) may also provide limited support for ERF files.

To enhance compatibility, you can convert ERF to JPG or PNG using AnyConv for easier access and sharing.
