Ren Ng is the founder of a new concept photo taking camera called Lytro. A kind of camera that shoots photos which you can refocused the images at any time.
Lytro has announced its revolutionary point and shoot camera with built-in storage. It has an 8Gb, 16Gb stoage.

This sounds like very interesting technology and will put a lot of people's 'noses out' if it works and becomes widespread through the world of togs!
hasn't this been posted at least twice before (maybe even one by Kombizz)
Interesting stuff and brilliant and I can't pretend to understand all the theory. I've read -scanned- through the dissertation and it seems this technology will be unlikely to be of use to serious photographers for a long time due to resolution limitations, giving you something like a 1800x1200px image from a 100mp sensor at best - and not yet.
It looks like the production camera they have mooted will be a very low res affair (much less than 2.2mp, presumably) and of little interest to people here other than as a curiosity and proof of concept, It will be interesting to see the price. But even if it only amounted to a gimmick at this stage, I'd like one!
For serious photographers to whom 2.2mp is acceptable, to reach useful quality even this 2.2mp image will have needed heavy image processing, so those people who objected to Panasonic lens performance being a designed in combination of glass and software will have a large pill to swallow! You will also have a 300mb file for that resolution.
Effectively, it seems to take not only the quantity of light into account but the direction too and records all the information to different areas on the sensor. Put very simply, because that is all I can understand - another way of doing the same thing would be an array of say, 30 cameras all pointed at the same scene but focussed on a slightly different part of it. The information from all these sensors would then be combined into one file which, on the computer, you could choose which focus points you wanted to include in your final masterpiece. Unfortunately, for a 12mp camera, this would give a file size of over 1gb per image, so you'd need a pretty good computer, not to say 30 cameras. Of course, the cameras could not all be at exactly the same point in space at the same time, either.
Another way is taking a series of shots with your own camera on a tripod with the focus changed slightly for each. Then pick the one you want or take the ones with the range of sharp focus you want covered and combine them in Photoshop's image stacking.
The advantage this new system has is that the camera doesn't need to be a on a tripod and so could capture moving subjects. But there is a heavy price to pay for that and it doesn't look like mainstream enthusiasts, let alone professionals will be using it for a long time to come. Personally, I'm nor sure the trade off would ever be worthwhile except for very specialist applications.
It occurs to me that some form of focus bracketing, in the way that we have auto-exposure bracketing would be another way to go. A camera like the new little Nikon with its 60fps, loose off 4 on a portrait with focus starting just in front of your selected point to just behind ...probably not but food for thought
