  "description_en": "The Contax N Digital CCD Parameter Disc recreator rebuilds a camera-specific calibration disc from newly captured RAW dark and white frames. It derives white balance, defective-pixel and reference-image files, then combines them with colour matrices and tone curves extracted from another N Digital disc. The author reports comparison with a known disc but notes unresolved factory scaling details.",
