You're quite welcome. The ability to use it easily was the primary reason I plunked down the dough for Lightroom. I like that it was an empirical discovery and not some "rule". When I saw the comparison between the various "rules" and the diagonal method when applied to the Mona Lisa, that was pretty much all the convincing I needed. For centuries, millions of people have been drawn to that enigmatic smile....and the diagonal hits it like a ton of bricks. I try to apply it to all my photos. Sometimes it isn't possible, but when it works, it really works well.
