Need to decide between Lightroom 6 and Lightroom CC. I travel often and seldom have access to the internet but still have to be able to get work done in Lightroom. How does this work?
Both software require momentary access to the Internet when you first apply the serial number in LR6 or you first launch LR CC.
After that, internet access is not required, except for once a month under LR CC to make sure your subscription is paid (and I have read that you can even have this check performed by phone if you don't have internet access at that time)
