I understand that if I open a DNG directly in ACR from Bridge it opens in a 32-bit instance of ACR, but if I open the DNG in PS from Bridge it opens in a 64 bit instance of ACR (on my 64-bit system). My question is, if I do some edits in 32-bit ACR and then close the file saving the parameters, and then reopen the DNG in 64-bit ACR later for more tweaking, I have not lost any potential quality by working the first time in 32 bit ACR, right? The 32 vs 64 bit distinction is only important when the parametric edits are actually applied, either in opening in PS as a rasterized image or exporting from ACR to TIFF or JPEG, correct?
As always, thanks!
