Adobe Bridge has been driving me crazy the last few days, I use it to add caption and keyword metadata to final hi res TIFF files.
Just now I had 17 files selected, created a new subkeyword, ticked it, and that wiped away all of the existing caption and keyword data I had already spent ages applying!
Yesterday similar problems - trying to to assign a set of keywords to a load of images, and the losing the Description, Creator, Sublocation, City, Country, Copyright IPTC Core data I had already spent hours filling in.
Anyone else seen this? I'm thinking it is possibly linked to how big the files are (Nikon D850 so each TIFF is around 70mb, Bridge used to be very reliable for this task but I'm going to have to look at using a different software app next time if it carries on.
PS - It is also wiping all of the camera EXIF data so I no longer see f/ stop, shutter, iso etc.
Select one of the problem files and use File > File Info then the Raw Data tab to check if the metadata still actually exists in the file. If it does, then this is just cache related affecting the display in Bridge’s GUI.
I replaced the problem files with original ones and re-did the work, I was using the latest 2019 Bridge, but went back to the earlier 2018 version which seems more stable and doesn’t have the same problems.
