Sigma RAW is the raw image format written by Sigma’s SD and dp cameras, saved with the .x3f extension. Its distinguishing feature is the Foveon X3 sensor behind it, which captures red, green, and blue at every pixel instead of interpolating colour from neighbouring photosites. The result is a raw file with remarkable per-pixel detail, though the trade-off is large file sizes and a narrower choice of compatible software.

 

How to open a Sigma RAW file?

Use Sigma’s own SIGMA Photo Pro. It is purpose-built for Foveon data and produces noticeably better colour and detail than generic raw converters.

 

Some third-party developers, including Adobe Lightroom, RawTherapee, and XnView MP, can open Sigma RAW files, but support depends on the camera model. Developing in SIGMA Photo Pro and exporting a 16-bit TIFF is the most reliable route into other editors. You can also convert the file with our X3F to JPG tool.

PostScript (PS) is a page description language created by Adobe that tells a printer exactly how to draw each page — the position of every character, line, and image — rather than storing the page as a picture. Because the description is resolution-independent, the same file prints crisply on a cheap office printer or a professional typesetter. PostScript revolutionised desktop publishing in the 1980s and is the direct ancestor of PDF.

 

How to open a PS file?

The standard tool is Ghostscript, a PostScript interpreter, usually paired with a viewer such as GSview or the built-in viewers on Linux.

 

On Linux, Evince and Okular open PS directly. macOS dropped native PostScript support after Mojave, so Ghostscript is needed there too. Since almost nothing outside printing workflows reads PS any more, converting it is usually the quickest solution — try our PS to PDF tool.
