CS5 supports ACR 6.x versions, CS6 supports ACR 7.x versions. CS5 wiil not read ACR 7.x. You either have to upgrade or use the free DNG converter.
So where do I find the free dng converter, I can still import them into my lightroom 4.1 as this is high enough a version I understand to see the CR2. Then maybe I can export those as tiff files for work in CS5
I have aslo read that DPreveiw offering a version 7 for cs 5 or am i very wide of the mark.
lastly do any third party developers offer a plug in for verion cs 5 that adobe do not.
I believe LR 4 supports 7.x raw.
Understand CS6 will now read future versions of ACR like 8.x but without enhancements. THis is allow new cameras to be read.
Do not think there are any 3rd party plugins for reading 7.x on CS5.
many thank Curt, hampered severely but not out. cheers
