O'k so I just noticed that when I use lightroom to do adjustments on images using my desktop, those adjustments aren't there when viewing those same images on my laptop. I was away last week end and decided to further work on some images I had and when I pulled them up on my laptop, the adjustments weren't applied. Is it the software on the desktop that actually does the "saving" of the adjustments and the external hard drive that just keeps the original? Or am I missing something?
