What is an ERF file?
The ERF (Epson Raw Format) is a proprietary raw image format generated by Seiko Epson digital cameras, specifically the R-D1 series. Structured as a TIFF-compliant file, it stores unprocessed sensor data directly from the CCD or CMOS image sensor, preserving high dynamic range and color fidelity prior to demosaicing. The format typically utilizes lossless compression or uncompressed storage to maintain data integrity for post-production, requiring specific Bayer interpolation algorithms to render viewable images.
How to open an ERF file
ERF files are not natively viewable in standard Windows or macOS image viewers without codec extensions. Professional post-processing software such as Adobe Photoshop (via Camera Raw), Adobe Lightroom, and Capture One provide full support for decoding and editing the raw data. For free alternatives, users can utilize RawTherapee or Darktable, which contain the necessary libraries to interpret the specific sensor data from Epson hardware.

What is a TIFF file?
The Tagged Image File Format (TIFF) is a container format for storing raster graphics images, originally created by Aldus Corporation in 1986 and currently controlled by Adobe Systems. Ideally suited for photography and desktop publishing, TIFF supports multiple color spaces (CMYK, RGB, Lab), various compression schemes (lossless LZW, Deflate, or lossy JPEG), and data tags that define image geometry. It conforms to the TIFF 6.0 specification and can accommodate multi-page documents and extensive metadata standards like Exif, IPTC, and XMP within its header structure.
How to open a TIFF file
Due to its status as a standard industry format for high-quality imaging, TIFF files possess robust native support across major operating systems, including Microsoft Windows Photos and macOS Preview. For advanced editing and layer manipulation, professional raster graphics editors such as Adobe Photoshop, GIMP, and CorelDRAW are required. Specialized viewing software like IrfanView or XnView can also render multi-page TIFFs that standard system viewers may display incorrectly.
