What is MIME type "image/x-olympus-orf"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

image/x-olympus-orf is the MIME type for raw image files produced by Olympus digital cameras. These files hold the camera's unprocessed sensor data in a raw format—typically with the file tagged as ORF. This allows for maximum detail retention and advanced editing later.

• Main use: Preserve all original image data for high-quality post-processing.
• Data storage: Includes sensor output and detailed metadata like exposure and white balance.
• Editability: Offers greater control over adjustments, such as contrast and color correction.
• Software requirement: Needs specialized tools (e.g., raw converters or editors) to display and convert the image into standard formats.

This format is part of the broader group of camera raw formats. Similar types include CR2, NEF, ARW, and others. Each is tailored to different camera brands but serves the common purpose of maximizing image quality through unprocessed data.
