Straight conversion to black and white using Lightroom then exported to Photoshop to apply selective dodging and burning. What I did is to make a new layer on top of the background (the black and white image) and fill this new layer with 50% gray. Then by setting this layer to OVERLAY blending mode, I can now selectively dodge and burn any part of the image using the brush tool on this new layer. White for dodging and black for burning. Normal setting of the brush would be OPACITY = 100% and FLOW = 3%. Hope this helps.
