    Google for some guides for 'selective coloring'

    Basically make a copy of the layer. Make the bottom one B&W and the top one color. Then erase anything in the top layer you don't want to be color

    I'd do it slightly differently:

    Create a Duplicate Layer on top and convert the top layer to B/W through your method of choice (Desaturation or otherwise). Put a layer mask on the top level and then use whatever brush you want to "draw" in the area you want colored.

    Looks nice. You can also go into the Layer -> levels menu on the B&W and increase the contrast. Try making the blacks blacker.

    A layer mask is used to only make selected parts of a layer visible. When you first create a layer mask, it's solid white, blocking the entire layer. When you do anything to the layer, the darker parts of the layer become visible. It's kind of like putting a piece of paper over the layer so you can't see it and then cutting holes in the paper.

    Can others edit my Photos:
    Photos OK to edit
    I sometimes find it helpful when doing the mask to put a semi-transparent solid color layer between the color and B&W layer to make it very easy to see what's masked and what's not.
