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 a PS file?

PostScript (PS) is a dynamically typed, concatenative page description language developed by Adobe Systems, serving as the predecessor to the PDF format. It describes text and graphics on a page using vector graphics instructions rather than rasterized pixels, making it resolution-independent. A PS file contains a program written in the PostScript language, which is interpreted by a Raster Image Processor (RIP) to generate the print output. It supports distinct imaging models, including Type 1 fonts and color separations, and became the standard for desktop publishing and high-end printing workflows in the 1980s and 90s.

How to open a PS file

Opening PS files requires software capable of interpreting the PostScript language, as modern OS image viewers do not support it natively. Ghostscript is the standard open-source interpreter used to view and convert PS files. For GUI-based editing and viewing, Adobe Illustrator and CorelDRAW can import PS files. Users can also convert PS files to PDF using tools like ps2pdf (part of the Ghostscript suite) for easier accessibility.
