I don't take a lot of flower shots, but was interested in this magnolia in the garden of the Episcopal cathedral in my hometown. Just got Lightroom 5, and played with the NEF (yeah, I shoot a Nikon). It was a random attempt, moving this slider, then that one. Close inspection shows odd halos around the yellow section in the center of the blossom. I need to watch some videos or get a book...
