SD1 to DIS Conversion: FAQ

What are SD1 files?

The SD1 extension is attached to RAW images captured using some models of Sigma cameras. Sigma is a Japanese brand producing various types of photographic devices and cameras. The brand is best known for its lenses that can be used on cameras manufactured by several other companies, including Nikon, Canon and Panasonic. SD1 is part of a group of extensions attached to images shot in RAW mode on Sigma devices, including SD0 and SD2. All are considered rare and probably difficult to open using regular image viewers.

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.
