Convert ORF to TIFF

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.

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.

The Tagged Image File Format (TIFF) is a container format for storing raster graphics images, originally created by Aldus Corporation in 1986 and currently controlled by Adobe Systems. Ideally suited for photography and desktop publishing, TIFF supports multiple color spaces (CMYK, RGB, Lab), various compression schemes (lossless LZW, Deflate, or lossy JPEG), and data tags that define image geometry. It conforms to the TIFF 6.0 specification and can accommodate multi-page documents and extensive metadata standards like Exif, IPTC, and XMP within its header structure.

Due to its status as a standard industry format for high-quality imaging, TIFF files possess robust native support across major operating systems, including Microsoft Windows Photos and macOS Preview. For advanced editing and layer manipulation, professional raster graphics editors such as Adobe Photoshop, GIMP, and CorelDRAW are required. Specialized viewing software like IrfanView or XnView can also render multi-page TIFFs that standard system viewers may display incorrectly.
