I have thousands of DNG files processed by the ACR versions that came with CS4 and CS5. I was hoping to re-process some of them with the later ACR versions that came with CS6. But when I open a previously edited DNG file in ACR 8.4, it seems to revert to the earlier version in which the file was originally edited/processed. I made a duplicate of a file and reverted it to Default--sort of like restoring its virginity--but ACR 8.4 was not fooled; it still opened the earlier version. What to do???????
The earlier version of ACR was using a previous Process Version.
If you want the newer adjustment sliders, set your Process Version to 2012 on the Camera Calibration tab.
Yes, that did it. I had noticed the process version message when I tried to open PV 2012 in the "old" ACR sporting PV 2003 or 2010, but I did not think of the opposite.
