Sort of yes and no is my opinion. The thing about toning is that it works on some subjects more than others, whereas straightforward B & W has a simplicity which is ultimately more applicable to more subjects. Again, purely personal opinion though, but Lightzone styles is nicer and a lot easier to use than Duotones, Tritones etc in Photoshop. On the subject of which converts better film or digital - to be honest not that much in it under ideal conditions but I still think film has the edge. Anyway example 1 converted from a Provia scan, tone mapped and converted to Platinum in Lightzone, example 2 straight conversion from digital using channel mixer in PS.
Sorry they open at different sizes, laziness on my part.
