What is a PEF file?

The Pentax Electronic File (PEF) is a proprietary raw image format developed by Pentax (now a subsidiary of Ricoh) for its digital single-lens reflex (DSLR) cameras. Based on the TIFF (Tagged Image File Format) structure/EP standard, PEF files store unprocessed sensor data captured directly from the camera's CCD or CMOS sensor, retaining a higher dynamic range and color depth (12-bit or 14-bit) than compressed JPEG counterparts. The format encompasses metadata such as ISO settings, shutter speed, and white balance, often employing proprietary lossless compression to manage file size while preserving absolute data integrity for post-processing.

How to open a PEF file

Operating systems including Windows and macOS offer limited native previewing of PEF files through built-in raw codec packs, though support varies by camera model. For comprehensive editing and non-destructive processing, dedicated raw converters are required. Adobe Lightroom and Adobe Camera Raw are the industry standards for PEF manipulation; free open-source alternatives such as Darktable and RawTherapee utilize the dcraw library to interpret the specific sensor data.

What is an EPS file?

The EPS (Encapsulated PostScript) format is a legacy vector graphics standard developed by Adobe in the late 1980s. It contains PostScript page description language commands describing 2D vector graphics, bitmap images, and text. Conforming to the Document Structuring Conventions (DSC), an EPS file includes a BoundingBox comment that defines the rectangular area of the graphic. It is strictly a single-page format intended to be embedded within other PostScript documents, often containing a low-resolution TIFF or WMF preview for onscreen display.

How to open an EPS file

While native OS support for EPS is deprecated in modern Windows and macOS (Preview no longer supports it as of macOS Monterey), professional vector editors are required for manipulation. Adobe Illustrator and CorelDRAW are the industry standards for editing EPS syntax. For viewing or rasterizing without expensive software, users can utilize Ghostscript, Inkscape (open source), or EPS Viewer. Converting to PDF is often recommended for broader accessibility.
