I’ve recently noticed that a DNG generated by DXO Photolab 6.16 opens differently in Photoshop ACR (CS6). It opens in an old process.
Reverting to 6.15 cured it.
Probably not many people using CS6 and so perhaps not affecting anyone else, but interesting. Seems the DNG output from DXO regressed 6.15 to 6.16.
