Did this a while ago... the model is a makeup artist who used makeup to make himself look older. The older man is looking at his reflection as a younger man. We used a mirror and combined two different images into a composite with the older and younger versions of himself.
Reflection theme photography can spice up a simple picture into an eye conic one. For this category you must have a good knowledge of angles, good perspective and vigilant artist's site. I have found this amazing reflection image on web. Check it out.
