I just received my first edition of Darkroom, the Lightroom user magazine published by Scott Kelby and the guys at NAPP. I must say...I was a bit skeptical as to what all I could glean from this magazine because I am pretty familiar with using LR now; however...
They had an article in this first edition on tethered shooting and they tell you how to use LR with it and give you all the details of setting it up.
I did it and it is great and opens up wonderfully new possibilities for me to do some controlled location shooting.
Chock one up for the NAPP guys again...definitely worth my $99 a year (just in BH photo shipping savings alone).
