Mongo has a technical problem/question.

He is currently using ACR 6.7.1 in photoshop CS5. It works fine. However, this version is NOT capable of reading and working on D4s NEF files. To read and work on D4s files in RAW, Mongo would have to update to ACR version 8.7.1. which is not a traditional ACR but a DNG converter.

Mongo is otherwise very happy with ACR 6.7.1 and does not want to bugger that up by installing a DNG converter in its place.

Questions:-

1. is it possible to leave the ACR 6.7.1 as a photoshop plug-in and download and use DNG 8.7.1 as an independent stand alone program on his Mac OR will installing DNG 8.7.1 automatically do away with and take the place of ACR 6.7.1 ???

2. do not really understand the difference between ACR and DNG converter - is it critically different ??

any help would be greatly appreciated
