This is the third image in my St. Annes sunset series (the first two are here and here) and may well be my favourite of the four.

This one was converted to black and white using the channel mixer (as described in my Black and White: part one tutorial), then toned using the selective color tool (see my Toning Colour Images tutorial).

On a related note, and as you'll see if you read the 'latest news' bit below, you can currently sign up for one of three of our Photoshop tutorials for free. Our Toning Colour Images tutorial is one of these so, if you're interested in finding out a bit more about the toning techniques I use for both my colour and black and white images (e.g. curves, selective color, channel mixer), sign up for that one.
