I don't usually rename original files at all. I also only use a simple Year/date folder structure. So instead I use keywords and IPTC Scene codes, as well as geolocation data to manage all of my images. I think the nature of what you shoot is important though. If you are a pro mostly shooting once or only occasionally for a variety of different individual clients, then DAM is pretty easy, since you can use a client centered folder structure. In my case where I'm shooting aircraft mostly at airshows it gets complicated real fast. There become a large number of different ways I'm going to need to sort the subjects of the images. This is when a database based system becomes ideal. Adobe have actually incorporated Lr style smart collections in Bridge. Unfortunately when you point a Bridge Smart Collection at a set of images it has to open every image in that folder tree to read the required EXIF/IPTC data to see if the image should be included in the collection. That is not going to be very quick when I have 67353 master photos in my Lr catalogue. I tried it before, when my catalogue was at least 10K images smaller, and it pretty much just kept reading the disk looking for matches.
So I'm guessing the DAM feature is going to be a non starter for me at the moment, even if there were an easy way to transfer from Lr to Luminar with libraries. Can it read Adobe .xmp files, and import the EXIF/IPTC data from those? I already write those so that Bridge can see the data too.
