Mark, no worries re exposing (fnarr fnarr) the technique. I scan using Silverfast with Photoshop. I set the image type to colour negative (which is why it's still colour and not monochrome despite what my first post may have led you to believe) and then in the film type selection I choose
Other/Other/Monochrome or in some cases
Other/Other/Macophot 25. To put that in context, a more typical setting for scanning colour film would be
Fuji/Superia/100. If I use those setting with the Fortia the resulting scan looks crazy and bar setting up my own custome profiles (me no time) using the above setting(s) is the best way for me to achieve this affect without any involved manipulation in Pshop afterwards...although I suppose that this technique qualifies as cooking the books somewhat anyway, right?

Leon: Thanks so much for the Simon Norfolk comparison. He is one of the current crop who I really rate and I love a lot of his output. I would never have seen it had you not mentioned it, but yeah, those first two definitely are headed into Norfolk territory (not that I'd presume etc.). I'm chuffed now. You've made my day.
