I always like to test new things, and many many moons ago I tried Picasa and didn't care for it all too much. However I like to give things a try every now and then and I really love how it does facial recognition.
However I am in a dilemma that I have 30,000 photos that I would like to re-process with improved tagging by using Picasa (or something else).
Is this even possible? It seems that I run a high risk of altering my files to try to cross-manage.
