RDC to STP 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.
