This is a simple shot.  It was thought out prior to being on location.  Even if you don’t have a 35mm wide angle lens, you can apply 2 techniques: sunlight on the faces, and use a short ladder.

It’s the angle which gives this a creative, fresh look.  The color photo was fabulous, but this is where Photoshop is so useful.  Turn the image into black and white, add a hue adjustment layer and mask out everything except for one pair of sunglasses.  Subtle touches make a big statement.  Once, again: it’s about controlling the elements.  Have fun!
