I may rely on B&W conversions too much but I love the tonal aspect of monochrome.
It may be because I am partially colour blind or maybe it is because I am of an age where reportage was in broadsheets and they were black and white.
LR 4 for exposure adjustments & Framing / straighten / crop-> Topaz B/W Effects for contrast / grain / shadows etc -> back to LR for any sharpening.
Topaz is a bit clunky with lightroom, requiring a host app to run inside. However Topaz provide that host gratis so it isn’t all that arduous to work with.
