MEF to DIS Conversion: FAQ

What are MEF files?

MEF is the proprietary RAW image format of Mamiya cameras. This high-end Japanese brand is well known among professional photographers for producing photographic equipment and has a history dating back to the 1940s. Also known as "digital negatives", RAW images represent uncompressed images which need to be customized using an editing program. They are often favoured by professional photographers for offering high-quality images including a large amount of details, which can be highly suitable for printing.

What are DIS files?

The DIS extension is associated with the DKB Ray-Tracer, a piece of software originally created by David Kirk Buck and Aaron A. Collins, which served as a predecessor for the POV Ray-Tracer. The latter software has the capacity to generate images from text-based scene descriptions and works on various platforms. Though fairly popular on PC/MS-DOS platforms at its release, the DIS format is now obsolete. It can, however, be viewed and converted to more accessible formats.
