I came across this yesterday... It's not about photography per se, but it does have an impact on photography of sorts.
Start with this image:http://www.cgarena.com/freestuff/tutorials...x%20Wysocki.jpg
If you've seen the 'Lord of the Rings' movie series it will probably look familiar, and the movie did provide some inspiration for the image. However, this is not a photograph. It's a rendered graphic image created by someone using a computer. Granted he did use an image of a person's face in his creation, but this image doesn't exist except in 1s and 0s...http://www.cgarena.com/freestuff/tutorials...telf/index.html
I think that as far as CG is concerned (rendering a 3D scene to a 2D picture) we've jumped light years in the last five years... Especially in speed an efficiency.
There are however 'serious' issues in CG that need to be addressed. I can't recall where I read it, but there was a study carried out by a fellow (Japanese) who builds automated robotic 'humans'. In it, he basically said, that humans are instinctively aware of 'perfection' and are essentially engineered to fear it, or be weary of it. He'd begun noticing it, when his robots started to get very close to real looking... People would admit it looked realistic, but everybody instinctively knew it wasn't real.
After completing the study, he (earlier this year) had a tech talk with a robot that was an exact replica of himself, wearing the same clothes, both sitting next to each other, and the robot tied into all his actions (facial movements) and basic gestures. With it, he attempted to prove a point that imperfection was part of the human intuition on the feeling of being safe...
Ah, it was a long time ago I read that, so it's rusty in my head. But he did say, that the same concept applies to CG, and that imperfection is what makes an image realistic.
For me, that image doesn't do a lot. ' But it demonstrates the point that for a CG to be convincing (ultimately) it needs to be less perfect in the design.
