I wasn't going to upgrade from LR4.5, but I did, mainly to justify getting the LR5 Tutorial (just kidding!). I thoroughly enjoyed the videos, and adding Eric Chan again really energized and enlightened the discussion on the thinking behind the code. The demos of the new features as well as the JDI stuff were clear, easy to grasp, and as usual, just entertaining enough to make the learning painless.
I am left with only one question: I don't understand the use of the Reanalyze control in the Upright section.
Anyway, thank you Jeff, Michael, Chris and Eric for a great job!
