I trialled cc Photoshop.
I had Photoshop CS4
and lightroom 4.4.
I used LR4 and cc as well as CS4 during that time
when I uninstalled cc
after initial work in LR4
I try to open it in PS4
it no longer recognise my Cr2 (Canon Mark 111 tif files)
(which it had no problem with previously.
When I try to go from LR$ to PSCS4
it now tell me
this version of Lightroom may require the Photoshop Camera Raw plug-in version 7.4 for full compatibility.
Please update the Camera Raw plug in using the update tool in the Photoshop help menu.
Ihave downloaded this off the net but it does not seem to solve the issue
