ORF to DNG Conversion: FAQ

What are ORF files?

ORF is an image file extension associated with RAW images captured with Olympus cameras. While most amateur photographers prefer shooting in a more accessible format, like JPEG or TIFF, which includes predefined features to correct aspects such as lack of brightness, color depth or noise, professionals mostly choose to shoot in RAW mode. Though ORF images can be up to 6 times larger than JPEGs or other compressed formats, they include a significantly larger number of options to add digital adjustments and change the image according to how the author wants.

What are DNG files?
