ISO 3200 Highlight Destruction in ACR vs Hasselblad Phocus and Iridient Developer (Dolls)

This page shows how Adobe Camera Raw 9.9.0 destroys a huge amount of perfectly-exposed high-key detail at ISO 3200 (and almost certainly other ISO value as well). No ACR settings could be found that avoid this wantonly destructive behavior.

The case for this being a serious Adobe Camera Raw BUG* is proven with RawDigger histograms and by showing that both Hasselblad Phocus and Iridient Developer delivers a high-grade image free of the problems seen with Adobe Camera Raw.

This bug also exists in Adobe Photoshop Lightroom, which shares the same ACR engine for raw conversion with Photoshop. Whether this Adobe Camera Raw bug affects only Hasselblad X1D 3FR raw files, or whether it is a general bug was an unknown as this page was being prepared. That would depend on having a camera like the X1D with fake/bogus high-ISO raw files**. But it does not affect, for example, the Nikon D810***.
