As great as single camera photography has become, it will never be “real”. By that I mean that all two dimensional imagery is viewed as referential information as it is processed by the brain. There is no confusion as to whether or not a photograph is real – or an image of something that is real. It is perceived as an image of something – it is referential imagery.
3D autostereoscopic life size photographs, on the other hand, make it possible to present an image to the eyes that the brain can process as real. Indeed, the brain does extra processing for three dimensional images. All sorts of extra things happen when viewing a 3D photograph. One theory under investigation is that the brain spends more time searching for comparable real imagery information that has been seen before to act as a comparitor to what is being viewed in the 3D photograph.
What this translates to is a dramatically more engaging process and one that evokes more brain memory processing. The ramifications of this are enormous for advertising and point of purchase information displays. But it is also important with regard to how we perceive portraits. Specifically, baby portraits. A life size 3D autostereoscopic baby portrait has the potential to evoke the same emotional response and feeling as looking at the baby in real life. This makes it a very unique momento. It is truly a moment captured that can be re-experienced for a lifetime. No other imagery does this.
