I just updated my "TLR B&W Conversion" action set to version 1.0b. The new version adds two new actions. Now you can make high contrast B&W conversions using a pair of Hue/Saturation layers, paired Selective color and Hue/Saturation layers, or paired Curves and Hue/Saturation layers.
I think most photographers will prefer the action using paired Selective Color and Hue/Saturation layers or or paired Curves and Hue/Saturation layers. While you can achieve similar results with any of the three techniques, adjusting selected colors by adjusting their CMYK values is more analogous to how filters work. If you are a B&W film photographer who moved to digital, you might like the paired Curves layer and Hue/Saturation layer.
In addition to the updated action set, I updated my tutorial and my learning gallery to get you started with the technique.
