An ORF file is a digital image file format used by Olympus cameras. This file format is similar to other raw image formats, such as CR2 for Canon and NEF for Nikon, in that it contains unprocessed image data captured by the camera’s image sensor.

Unlike other image formats, which are processed by the camera’s built-in software before being saved to the memory card, ORF files are saved in their raw and unprocessed state. This means that the photographer has greater control over the final image, as they can adjust parameters such as exposure, white balance, and color saturation during post-processing.

ORF files are typically larger than JPEG files, as they contain more detailed information about the image. While this can be a disadvantage in terms of storage space and transfer times, it can also be an advantage for photographers who want to capture the highest quality images possible.

To work with ORF files, photographers need specialized software that can read and process this file format. Many popular image editing programs, such as Adobe Photoshop and Lightroom, support ORF files natively. Alternatively, photographers can use software provided by Olympus, such as Olympus Viewer or Olympus Workspace, to work with ORF files.

In conclusion, ORF files are a raw image format used by Olympus cameras. They contain unprocessed image data that allows photographers greater control over the final image. While ORF files may require specialized software to work with, they offer the potential for higher quality images and greater creative control.
