RDC to FITS Conversion: FAQ

What are RDC files?

RDC is a RAW image format associated with Rollei cameras. This German brand is well known for the Rolleiflex and Rolleicord series, which include several high-end models that were initially developed in the 1930s and developed throughout the following decades. In the early 1990s, the brand became part of the South-Korean group Samsung, but nowadays it is again based in Germany and continues to provide medium-sized, 35mm and subminiature cameras for an exclusive target public. The RDC format can be opened by a limited number of viewers, so the best option is to convert it to a better known and more accessible format, such as JPEG or TIFF.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
