So, with two programs from Adobe with the same Engine I had the hope that if I made a change in one program it would be reflected in the other. Not always the case it seems. For example, if I make some corrections in LR (with "automatically write changes into XMP" checked in catalog settings) and then open bridge I see the changes. Perfect. However, if I open an image in Bridge and tweak then that change wont reflect the next time i open LR (lr still uses its database I guess). I know I can go into the "photo" menu in LR and "read meta data from file", but that seems clunky and inefficient. I'm in a situation in which someone else may make changes in bridge to a file and I wont know it when I go into LR. Is there a switch I'm not flipping?
I don't think you're making changes in "Bridge," per se, but rather using Adobe Camera Raw accessed by Bridge.
It is my understanding that adjestments to raw images made in ACR actually affect the raw file ... while adjustments made in Lightroom do NOT actually affect the raw file, but in fact all changes are stored in separate files
that are in relationship to the raw file, withOUT affecting it at all.
For this reason, when you make adjustments to the raw in LR you will
not see the changes to the raw file in Bridge precisely because
there were no actual changes made to the raw file by LR. Every "change" you see in LR is (in essence) a "filter file" through which Lightroom interprets the raw image, without actually touching it.
Only when you "export to .tiff" do you now have a new file, based on Lightroom's influence, but yet the raw file remains untouched. IMO, this is far preferable to actually altering the raw image.
