I recognize that there are UI differences between the two programs e.g. the Basic panel in LRC is split into 3 panels in ACR and other various small differences) and I realize that the Main purpose of LRC is cataloging. My question is: Are there any functional difference between the two? Are there any tools or functions that you can do in ACR that you can't accomplish in LRC or vice versa? I'm just asking the question about ACR and not Photoshop. I realize that PS is more comprehensive.
