The Wonder of Blue Filter

(Leica D-Lux 5)
How to produce a photo like this, brightening up a part and blackening out the rest?

The original image was done in colour and given a yellow hue by the street lamps.  In post processing, add a blue filter effect to taper off the yellowish tone of the façade into the shadows; or in other words, to darken the yellowish area in the image.  Now the corridor was lit up by florescent lamps so the area is bluish and is unaffected by the blue filter. The end result is the accentuated contrast between the bright and dark parts.  For more dramatic effect, tune up the amount of highlight or exposure and turn the image into black and white.  Viola!
