Anthony Morganti uses an interesting technique to create photos with a black and white HDR look in Lightroom. It can transform a photo so it looks something like this. (I added a vignette as well.)
It doesn’t suit all photos of course, it’s also only a starting point as you should develop your photos in whatever way you desire. To avoid repeating all those steps every time I created a Lightroom preset.
Grab that file and install it in the same way you’d install any Lightroom preset. What d’you think?
