Hey Bob, this is an interesting thread. I knew that LR had its own camera raw built in, and that PS and Bridge used the external camera raw. I just have my Creative Cloud set to automatically update all apps, so I don't pay attention to it. Just update it and forget about it. And of course, all of those apps are stored on my internal SSD.
But this made me think. I love Bridge. It is a fantastic photo organizer and viewer, and it displays your raw files with all LR edits applied if you have sidecar files (which in my opinion everyone should have). I wish two things:
1. That LR would use Bridge in its library module. In other words, LR closely tied to Bridge or have Bridge embedded.
2. That Bridge was linked to the LR cat so that we could use the much more powerful Bridge to do surgery on our file and folder system and have it applied to the cat.
