What is an ORF file?

The Olympus Raw Format (ORF) is a proprietary raw image container developed by Olympus (now OM Digital Solutions) for its digital SLR and mirrorless cameras. It stores the unprocessed data from the image sensor, including the Bayer filter mosaic information, alongside headers describing color temperature, saturation, and contrast settings at the time of capture. Unlike processed JPEGs, ORF files maintain a higher bit depth (typically 12-bit or 14-bit), allowing for extensive post-processing latitude regarding exposure and white balance adjustments.

How to open an ORF file

To view or edit ORF files, users should utilize OM Workspace (formerly Olympus Viewer), the manufacturer's dedicated software. Universal raw converters such as Adobe Lightroom Classic, Capture One, and DxO PhotoLab provide robust support with specific lens profiles. For free, open-source alternatives on Linux or Windows, RawTherapee and Darktable can decode and edit ORF files using the LibRaw library.

What is a PDF file?

The Portable Document Format (PDF) is a comprehensive file format, standardized as ISO 32000, designed to present documents consistently independent of application software, hardware, and operating systems. It encapsulates a complete description of a fixed-layout 2D document, including text, fonts, vector graphics, and raster images, based on the PostScript language. Advanced implementations support interactive form fields, JavaScript scripting, 3D objects (U3D/PRC), and various encryption standards.

How to open a PDF file

PDF viewing is natively supported by all major modern web browsers (Chrome, Edge, Firefox, Safari) and most operating systems via built-in previewers. For advanced manipulation, form filling, or pre-press validation, dedicated software such as Adobe Acrobat DC, Foxit Reader, or open-source tools like Ghostscript and Poppler is required.
