Thanks, Brian. I suspect LR 5.4 or the soon to be released 6.0 would suit me fine. However, my partner has the Photoshop CC for her work and it can be added to my computer also so that seemed the easiest (and cheapest since it's already paid for)absent technical complications. But that's an issue for me to decide, not for the forum. I will check out the price and specs, etc of 5.4 and 6.0.
