File extension .erf
Category Image File
Description The ERF file format is the RAW image format used by Epson cameras. Many photographers like to take their photos in RAW mode as this allows them to control the creative editing of an image and they can play around with the various settings around colour correction and white balance before they decide to convert to a more mainstream format.
Technical Details ERF files are generated by the Epson R-D1 and R-D1s digital rangefinder cameras, Epson ERF files are based on the TIFF/EP specification but deviate slightly including the use of a non-standard file header, the inclusion of additional image tags and the encryption of some of the tagged data.
