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!
