I like the simple stuff in BW images. Either I shoot in camera BW or color than convert. I only work with the, Contrast and Levels to do my post processing, that's it. And of course Sharpen, then Unmask Sharpening. For the web... always sharpen after resizing your image.
It's all in your eyes of how " you " want it to look as far as the tone of your image. It's like art.
