Biology + Psychology + Technology = 3d

The eyes are NOT film cameras. So stop trying to 'think' like a camera when you are trying to visualize a shot or a frame or a scene... This is the first major hurdle when you are a 'died in the wool' time-served 2d director such as me. 13 years in London, 2 years in the States, 6 months in Belfast, 6 months in Cardiff, 4 years in Manchester. That all adds up to 20 years of years 'thinking in 2d'!
To create good watchable stereo 3d that doesn't pull your eyeballs out of their sockets, you cannot rely solely on the Technology. You have to begin with 'how we see' and how the brain uses 'what we see' and combines that information with a whole load of other factors before you even get a camera out of the case...
At this point in the blog I should bring into the frame my new best friends. Dr Bernie Harper and Rob Black. They are from Liverpool University Psychology Dept and they eat, sleep, drink, walk, talk, 3d! They think and communicate only in 3d! It took some adjustment from them to be able to talk to a numpty director like me and start to explain and unravel some of the complexities of stereo 3d. Dr Harper (Bernie to his friends) has been 'doing' 3d research for 10 years and knows more about 3d than is good for the mortal man... Rob Black on the other hand is a Perception Specialist / Consultant and he can show you things in 1d, 2d and 3d that you never knew existed! So Liverpool University, has a world renowned psychology dept. and I would have access to some of their greatest minds to help me learn about 3d. I was psyched
Who was it that said? : "I could teach you everything there is to know about 3d in an afternoon, but it would take you a lifetime to understand it." Sorry if that is a bad quote, but it make the point. It is such a complex area that if you fancy having a go then good luck. Throw yourelf into it and prepare to fail! And understand you cannot 'fix it in post' - It doesn't work like that!

Stereo 3d and Liverpool University

My few baby steps in learning how to shoot stereo 3d produced some results...
A very impressive anaglyph quicktime that when you watched felt like an alien spaceship was hovering above your head and was sucking out your visual cortex with a Star Trek transporter!
clearly I had a way to go...

Enter LIVERPOOL UNIVERSITY in the North West of England.

As a self confessed 'businessman' in the film industry, I applied to the Regional Development Authority for a Training & Innovation Grant', and I was absolutely amazed when I was successful! Great, I thought, I'll be heading down to Pinewood, Britains very own film industry, to play with the professionals and learn all their secrets... but NO, it was not to be. What happened was that the Innovation Grant wasn't money in your hand, it was 'training to the value of...' with one of the regions 'knowledge providers'. Which I found out in my case was to be Liverpool University. What could I learn at my age and with my experience in the film and tv industry, by going back into 'academia'??? The answer, as it turns out, is a fantastic amount.

Stereo 3d is 1/3 biology 1/3 psychology and 1/3 technology.

This is the first BIG thing to learn in stereo 3d, especially as a director and stereographer.
Learn and understand the biology of the human vision system (also known as 'eyes').
Our eyes are NOT video cameras, they don't zoom or 'pull focus'. they are NOT 3d imaging devices.
Learn and understand the psychology, or in other words how your brain 'sees' - How it interprets the monoscopic depth cues to provide a depth map of the environment and how it combines all the information from all its 'sensors' with sight, and also how the brain combines its existing data on imagery and spatial awarness to navigate us and help us interpret what we see...
Learn how the technolgy that is available to us as filmakers and stereographers can be used to best effect to tell stories, evoke emotion and 'paint' 3d pictures based on reality...

As I start my training with Dr Harper and Rob Black I am getting to see the importance of at least getting a basic level of understanding of the biology and psychology of stereo 3d if I am ever going to be able t0 shoot and direct a high standard of stereo 3d.
The technolgy is easy in comparison! You hand over responsibility to the guys with the big rigs and hand over some serious bucks at the same time! BUT, I have learnt that you really need to get a thorough basic knowledge of 'how we see', and 'how our brains interpret what we see'. THEN you can play games with technology to do the film makers thing... and around creating non real 3d reality!

I think I may be turning into an OCD 'Ortho' Stereographer - or pehaps that should be OSD - Ortho Stereo Director!
As I carry on my stereo 3d jouney I have come across 'purists' portrayed as amateurs and Hollywood Stereo crews portrayed as 'Industry Experts' . But I am starting to worry about this battle over the I-O (the distance between the 2 cameras when filming)...
I need to go and find out more.
Stay tuned as I report back daily...
