Kirk - Thanks so much for your quick reply. I was not saving the adjusted TIF file over the original as I did not want to make destructive changes to the original scan. I was just clicking 'Done' and when I returned to Bridge the adjustments were displayed. What I did not understand is that adjustments made by clicking 'Done' could not be read and displayed by non-Adobe software like Photo Mechanic.
Fortunately the keywords and description in my TIF, DNG, JPG, NEF, ARW files created by Bridge can be read by Photo Mechanic and other non-Adobe software.
I will need to rethink my workflow and which software to use. My main goal is that my photo archive and adjustments made to the photos do not rely on any software publisher or system and can easily be moved to other software when desired.
Photo Mechanic seems like the best software to 1) browse & search my large photo collection, 2) create on the fly slide shows for my computer screen, 3) add and embed keywords and descriptions, 4) batch rename files, and 5) export to JPEG's when needed.
Hmmm. Lots to think about. I just do not want to keep paying Adobe every month!
