“I have some photo files saved in ORF format, but my computer failed to open them. How to solve this problem?” If you have an Olympus digital camera, you will get ORF files on the memory card after taking some photos. As a RAW image format, ORF has many benefits. But you will face some troubles when opening, browsing, managing, or editing them. Because ORF is a RAW file format with additional information, it is not compatible with some photo editors. What should you do with the ORF files? Here is everything you need to know about the file format.

How to Open or Convert ORF Files

Part 1: What is ORF File Format

An ORF file is the file extension commonly associated with Olympus digital cameras. This file format can store RAW images as well as metadata captured by your Olympus camera. It also indicates the file format, the way of encoding, and more information. You can select the RAW file format from the settings on your camera to get all data from the processor.

There are a lot of image formats, such as JPG, which is a compressed image format holding much less information. RAW files, such as ORF, are lossless. It means they do not lose any quality. The ORF file is at least 12 bits per pixel, while JPG only holds 8 bits per pixel. The rich metadata is helpful if you wish to adjust and edit your photos later.

Part 2: Possible Problems with the ORF Format File

1How to Open an ORF File?
There are only a few options for opening an ORF file, such as the Olympus Viewer 3 bundled in the CD. But the default photo managers on Windows and Mac cannot read the RAW photos directly.
2Can I convert an ORF file?
It is easy to convert ORG files to JPG format. Just select an ORG file converter to transcode the photo format. You should bear in mind that the metadata will lose after conversion.
3Can Photoshop open an ORF file?
Yes, Photoshop can open ORF files, edit the file format and convert the desired file to standard image formats. But it does not work for all versions of camera RAW.
4Does Lightroom support ORF files?
Lightroom can open and convert your ORF files of the Olympus camera. But you will need camera RAW 1.0. If you have the OM-D E-M1X, you will need 2.2 instead.
5Are ORF and RAW the same?
The ORF file is an extension of the RAW image format for the Olympus digital camera. However, RAW is a collection of file formats that include various file extensions, like ORF, NEF, CR2, etc.
6ORF or JPG? Which is better?
The answer is different depending on your need. JPG is used on mobile devices and the Internet. ORF, on the other hand, is a good option for original photos captured from cameras.
