Free Tool Fixes Nikon Z8/Z9 ISO 64 Shadow Anomaly

If you shoot Z8 or Z9 and you've ever wondered why ISO 64 looks slightly worse than ISO 100 in deep shadows, it's not your eyes — there's a genuine sensor-level noise distribution quirk at base ISO, and this free tool actually fixes it. Roughly 0.3–0.5 stops of shadow performance left on the table, recoverable in one click, with the corrected DNG dropping straight into your existing Lightroom or Capture One workflow. Niche, yes — but if you're maximising dynamic range on landscape or studio work where base ISO matters, this is worth five minutes of your time.
