Black & White tonality is something that I've been working on for a while. The best B&W images demonstrate a sharpness and clarity that serve to make up for their lack of colour with excellent subject clarity. This is one of my better recent efforts I feel - stations are tough because of the huge number of light sources which can cause overexposure of certain elements. Stopping down helps with this but then you lose the light advantage of larger apertures. However the D3 continues to show age is no bar to exceptional performance, handily producing clean images at ISO6400.
