The link to this critical plug-in for converting the new High Res RAW files produced by the E-M5 Mark II is here:
The hard part (at least for me) was finding where the Plug-In was after I installed it on my Mac, and the instructions provided by Olympus didn’t help much. Sorry Windows users, I can’t offer any help for you. 😦
So after a lengthy search, I finally found the plug-in living in a Plug-ins folder in my Mac’s Applications folder. Needless to say, Photoshop didn’t know it was there.
I just copied the OlympusHRS_ORF.plugin file to the Adobe Photoshop CC 2014 Plug-ins folder, and then Photoshop was able to find the plug-in and convert the High Res RAW files. 🙂
Once you’ve properly placed the plug-in in the appropriate folder, run Photoshop and go to the File menu > Import > High Res Shot Raw File Plug-in. The Plug-in will open and allow you to make some basic adjustments before opening the file in Photoshop. From there, do your magic in photoshop and then you can save the image anywhere in any format you want.
Hope this helps …
