ORF to DNG
File Converter

ORF stands for Olympus Raw Format, and it is the raw image file format used by Olympus digital cameras. This format stores unprocessed image data directly from the camera’s sensor, preserving the maximum amount of detail and allowing photographers to adjust various image parameters, such as exposure and color balance, during post-processing for optimal image quality.

DNG (Digital Negative) is an open-source raw image file format developed by Adobe, aimed at providing a universal and more standardized option for storing raw image data from digital cameras. This format enables extensive post-processing flexibility, allowing photographers to adjust exposure, color balance, and other settings while preserving image quality. DNG files also tend to be smaller in size compared to other raw formats, and they are widely supported across various software applications, making them a popular choice for photographers looking for both quality and compatibility.
