Achieving 'Nikon' B&W tones in Lightroom?
Try what I do when shooting B&W. I usually shoot RAW & JPEG Fine with the monochrome picture control. I used to shoot using Ilford HP5 so I raise the contrast in picture control and shoot at an ISO of about 800. This way I get 2 files the Jpeg which retains the cameras setting in B&W and then I have RAW file which I adjust in Lightroom to match the jpeg.
