To reach the space and to restrict the barriers between the illusion and reality is one of the biggest ambitions in the world of "Rendering", the one which is always called as "What's the reality anyway?" and "How to prove the reality". Is it just a simple vision or a touch of an object or do we need more justifications to prove the reality?

Renderers have recently gone extra miles enjoying the laws of physics and mathematical calculations that can help distinguish real and unreal images, noted that they have started a vast competition on image processing so far as there are rendered images in the world of today's photography considerably hard to distinguish whether they are real or not, even by dear photographers and other experts in this field.

So why consider this in "photography" anyway?
