What is an LFR file?

LFR files mostly belong to Lytro Desktop. The *.LFR file extension stands for Lytro Light Field Raw File, and it signifies an image format employed by Lytro cameras to capture light field data. Unlike conventional images that record only color and intensity, *.LFR files encompass directional light information, enabling refocusing and perspective shifts after the image is taken. This is achieved by the microlens array in Lytro cameras, which captures light rays from multiple angles for each pixel. The *.LFR files store this raw light field data, which is then processed by Lytro software to generate viewable images. The rich data within *.LFR files allows for computational photography techniques like depth estimation and 3D model generation.

How to open LFR files

Can't Open Your .LFR File? Try These Steps

Because .LFR files originate from various programs, they aren't universally openable.

1. Identify the Source: If from a light-field camera workflow, it's likely a Lytro Raw Image. If from an enterprise system, it may be a proprietary report.
2. Check the Header: Inspect the first bytes in a hex viewer or text editor.
   • "Lytro" or EXIF data suggests a camera raw file.
   • Readable XML/JSON indicates structured data.
   • "PK" means it's a ZIP archive.
3. Use the Original Software: The original program is usually required. Try Lytro Desktop or a compatible raw editor; if uncertain, ask the sender.
4. Use this Webpage: Drag and drop your file into our viewer to detect the format, extract readable metadata, and preview contents when possible.

LFR format details:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below is our analysis of the LFR files:

LFR is rarely used as a file extension and includes various formats for various programs. The following file formats are most commonly found in LFR files:

• 65% of all LFR files are associated with Lytro Raw image. They consist of unreadable binary data. The file size is in the range of 54 MB to 100 MB. It is a modern file type.
• 10% of all LFR files use the same file format, which can be identified by the letters "KF" at the beginning. These are binary files, so they do not contain words or text. LFR files can be up to 5 MB in size, but are often around 240 KB - 4 MB.

The remaining 25% of all LFR files are different files with different signatures. If you want to find out what your LFR file contains, drag and drop it onto this page.
