What are ORF files?

ORF file is a raw image format used in Olympus digital cameras. Like all other raw formats, it contains image information rendered directly by the camera's sensor.

What are the advantages and disadvantages of the ORF format?

The ORF format is a multimedia standard in the current world of digital content. And it shows the following advantages and disadvantages:


  • ORF files have so-called headers that present the characteristics of the image, such as saturation, color temperature, contrast, etc. The headers also contain metadata, which includes the technical characteristics of the camera.
  • Because ORF images are output without undergoing any processing, they exhibit near-real color and shadow characteristics, and are more open to extensive editing than JPEG or TIFF images.
  • The format allows users to achieve maximum precision by setting their own white balance and saturation values.
  • Allows camera sensor data to be saved without transformation or distortion


  • ORF file cannot be edited in a graphic editor without importing it to another format.
  • Limited number of programs for viewing.
  • Problems with format switching and saving (files are too heavy).
