What is a .ERF file?
ERF is Epson’s camera RAW format. Opened in Adobe Lightroom.
- Did you know
- ERF was used by the Epson R-D1, one of the first digital rangefinder cameras.
- ERF was the raw format of the Epson R-D1, which on its 2004 release was the world’s first digital rangefinder camera.
- The R-D1 that wrote ERF files accepted Leica M-mount lenses and beat Leica’s own digital M to market by about two years.
- The R-D1 was a joint effort with Cosina, pairing Epson’s electronics with a body derived from the Voigtländer Bessa rangefinder.
- True to its film-camera inspiration, the R-D1 made you cock the shutter with a manual wind lever between ERF exposures.
- What Analyser shows you
- Open camera RAW files from Sony (ARW), Canon (CR2, CR3, CRW), Nikon (NEF, NRW), Fujifilm X-Trans (RAF), Sigma Foveon (X3F), Olympus (ORF), Panasonic (RW2), Pentax (PEF), Adobe DNG and many more. Reads full EXIF and lens data, the true sensor resolution, GPS and histograms, recovers the Sony and Nikon shutter actuation count, and develops the RAW - decoding the sensor to a full-resolution image, or extracting the embedded preview when a true demosaic is not available.
