How to open orf files in lightroom

Supported image formats

The TIFF or TIF format (Tagged Image File Format) is used to exchange files between different programs and platforms. TIFF is a flexible bitmap image format that is supported by virtually all painting, image editing and page layout programs. Virtually all desktop scanners can produce TIFF images. Lightroom supports large documents in TIFF format (up to 65,000 pixels per page). However, most other applications, including older versions of Photoshop (before Photoshop CS), do not support documents larger than 2 GB. Lightroom can import 8-bit, 16-bit, and 32-bit TIFF images.

The TIFF format offers better compression options and industry compatibility than the Photoshop format (PSD) and is therefore recommended for exchanging files between Lightroom and Photoshop.

In Lightroom Classic, you can export TIFF image files with a bit depth of 8 bits or 16 bits per channel.
