I have upgraded from a Canon 60D to a full frame 6D When I am in LR and want to bounce over to CS6 using my lightroom adjustments I click the EDIT IN option from the drop down menu in LR and choose CS6... ps will load but the work area is blank. Now if I use a image from my files that came from my 60 D this dosent happen at all.The 60D images load right into PS to be further edited. This makes no sense to me and I hope it makes sense to someone else.
What version of camera raw do you have for PS? You should have at least 7.3 for the 6D.
