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 PNG file?

Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression, created as a patent-free replacement for the Graphics Interchange Format (GIF). Standardized as ISO/IEC 15948:2004, PNG utilizes the DEFLATE compression algorithm (a combination of LZ77 and Huffman coding) and supports palette-based images, grayscale, and full-color non-palette-based RGB/RGBA images. A defining feature is its alpha channel support, allowing for variable transparency levels, unlike the binary transparency of GIF. It does not support animation but offers gamma correction and interlacing via the Adam7 algorithm.

How to open a PNG file

PNG files possess near-universal compatibility across all major operating systems (Windows, macOS, Linux, Android, iOS) and web browsers (Chrome, Firefox, Safari) without requiring additional software. Default image viewers such as Microsoft Photos, Apple Preview, and virtually all graphics editing software including GIMP, Adobe Photoshop, and Paint.NET natively handle the format.
