ST4 to DIS Conversion: FAQ

What are ST4 files?

An ST4 file represents a RAW image taken with an SBIG CCD camera. SBIG is a producer of astronomical instruments and ST4s most likely contain images related to some type of scientific or industrial application. They are considered rare and are 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. 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.
