You have to use the correct Adobe Camera Raw for the correct program. CS3 means ACR 4.x. Use the LR5 ACR as that is more recent.
Does that mean that my ACR for CS3 was replaced by the on for Lightroom 5 when I installed it recently? I didn’t realize it was a separate program. I knew Bridge was but I assumed it was common to Bridge.
BTW. Thanks for your response. Thinking about joining PS CC but not sure how that works. I prefer stand alone so that I don’t need Internet constantly.
Lightroom will read ACR 8.2, which is what you need. CS3 will only read 4.x. They are separate programs.
PS CC does not need to be connected to internet constantly. Program is downloaded to your computer. Need to connect to internet at least once every 90 days.
Hope this solves your problem, or at least helpful.
Thanks. Very helpful. Wish I had known about PS CC before I spent over a year subscription on LR 5. So much trouble getting a serial number from the seller. Thank again.
