What happens if in photoshop under Edit>Preferences>File Handling if you uncheck Prefer Adobe Camera Raw for Supported Raw Files?
Unfortunately this does not help.
I still get the same error message:
"Could not complete your request because the file appears to be from a camera model which is not supported by the installed version of Camera Raw.
Please visit the Camera Raw help documentation for additional information."
As there seems not to be any simple solution to this problem, is there any form of bug report system to let adobe and the developers know?
I suppose there might be a problem between the fff-file-format of the hasselblad digibacks and the ones from the hasselblad flextight scanners.
Does the Hasselblad format (as facilitated by their plug-in, not Camera Raw) appear as a separate line item in the list of formats shown in the Photoshop File - Open As dialog?
If so, a workaround may be to choose File - Open As, then explicitly select the Hasselblad plug-in format.
You can report bugs on this forum: http://feedback.photoshop.com/photoshop_family
That actually did the trick.
Thanks a lot!
