Bridge CC is only a kind of Explorer to manage the images, however for Lightroom you would need to import the images in the Catalog and work on them.
Please let me know if you need any other assistance.
The images can be imported into Lightroom from their current locations. Since you are using DNG files, the adjustments to the raw images will probably be included, as will any changes you have made to the TIF and JPEG images. Lightroom will be reading the same images. It will be necessary for you to "copy" them into Lightroom. That would just double your image count and would really accomplish anything, in my opinion.
Just an observation and suggestion. I would suggest that you consider NOT having a set of finished images and another set of shipped images. My suggestion would be for you to just work with your master files. They are always in a finished state unless you make additional changes to them. If that happens, then it's necessary for you to export another finished copy. I would suggest just working with your master files and export copies when they need to be shipped. Ship the copies, and then give rid of them. You don't really need them, and they are just taking up space on your hard drive. As I indicated, this is just a suggestion. You are certainly free to manage your images as you see fit.
Thanks for assistance. I assume that I can safely copy my Adobe Bridge Photos straight into Lightroom ?
I have worked in Photoshop for many years but would like also to start using Lightroom.
I am ok for LR with new images directly from cards or camera but unsure if it was ok to directly copy previous images currently stored in Bridge into Lightroom.
You DO NOT COPY images into Lightroom. You Import a Reference to them. In LR click the Import button in the lower left hand corner of the Library module and Point the import to the location of your images on your hard drive.
LR is a image management Database system. No images get Copying into LR. They are References and remain where they are on your hard drive.
When importing images from a memory card you can Copy them from the memory card to a location on your hard drive of your choosing. That is all done in the Import dialog window.
Please view the online tutorials for the proper use of LR and or buy a book and read up on how LR works. It will save you a lot of headaches.
Your photos aren't stored in Bridge - they're just referenced by/visible in it.
You're still going to need to import them into Lr from whichever hard drive locations they're physically on.
Thank you so much for your straightforward answer which helps me greatly.
