3D Vision MUCH Different Than 2D Vision.


Spatial binocular disparity and motion parallax trigger brain activity that is considerably different than visualizing 2D imagery. Indeed, it affects different parts of the brain. Neuroscientists do not fully understand everything that happens with regards to the processing of pairs of 2D retinal images to form depth information within the brain. But they have been able to detect brain activity specific to the viewing of 3D objects. There is also observed psychological information that shows more than simply perception differences between 3D imagery and 2D imagery. 3D is not just an added feature or value add, it is a whole different way to present visual information that utilizes different areas of the brain to process.

When our brains process 2D imagery (photos, movies, etc.) we perceive the images to be referential. There is no confusion with regards to whether what we are looking at is real or just a representation of something real. When we start to present 3D imagery there IS confusion. Our brain is trying to determine if what we are looking at is real or referential. We have no understanding of this process or the ramifications.

What is the purpose of 3D vision? Well, certainly our ancestors used it to determine if a predator was running towards them – and how fast – so that they could precisely time throwing a spear or take a defensive action. One can easily reach a conclusion that 3D vision has been essential to our survival and success as a species.

I’m finding that my role as a 3D photographic artist must ALSO embrace the scientific nature of how humans process 3D imagery. I am making discoveries every day that are truly amazing and demonstrate how little we know about what goes on when we view a 3D image.

I am concerned about much of what I read on various group discussions because I haven’t read ANYTHING that addresses just how radically different 3D is. I see considerable content about 2D to 3D conversion. Such a process is a complete departure from anything natural concerning how we see and perceive reality. There is ZERO thought on the ramifications!

This is like jumping into an airplane and learning to fly for the first time by yourself as it is happening. There might be some successes – but the opportunity to crash and burn is VERY real.

Our industry can benefit dramatically from scientific research. But the first step is to realize that our knowledge base is extremely limited.

For myself, I have carved out a tiny piece to learn about and perfect. Specifically, it is the creation of the most life-like real imagery possible. To switch the “real” part of the brain on and the “referential” part of the brain off. To create imagery with the resolution and life size dimensionality that evokes the same emotions and brain activity as what happens when people look at the real thing. This narrow focus of specialty has taken me two years to realize that I know practically nothing and understand even less. It is extremely challenging – but the most rewarding work with which I have ever been involved.

I have only recently been testing the ability to suggest subliminal information within a dimensional image. Some results have left me stunned.
