Can lightroom 4.3 catalogue image be used with Photoshop CS5 camera RAW and be used non-destructively after editing in CS5? If Bridge is needed, how can Bridge access the catalogue without altering the catalogue and confusing LR? I use LR of my file orginization, not Bridge. Also, each time I go to edit in CS5 from LR4.3, a dialogue appears warning about the need for Camera Raw 7.3. Why? And how do I correct this? My LR is up to date as is my CS5.
