I think i prefer the warmer toned one at the bottom, although the blue does give a colder ambience to what is a wintery scene. Many years ago in another life when I did my own colour and B/W processing and printing in a proper darkroom (happy days) I used to print onto achival fibre paper and selenium tone them as opposed to sepia, which gave a similar tone to the last shot. Very subtle but very nice. Nice shots those as well.
I'm actually hankering after making a return to film and chemical photography just to do monotones, I've never got to love digital black and whitle like I did film, there's just something missing with it for me. In fact I've been scouring e.bay for a nice retro film camera, I used to have an old Franka rangefinder - like this:
A Field-day with the Frankarette but I can't find it anywhere. Not sure that Mrs Dewi would appreciate the house stinking of chemicals again though - so maybe she has something to do with it's disappearance.
