... and if it is. When do we get the Photoshop Plugin?

Looks fake to me.

If it is real it is amazing, but i can't see how any algorithm could possibly get that much detail of an out of focus blob like that.

Scientists used no adaptive optics to generate the enhanced image; the high resolution is due solely to computational image processing algorithms. (images courtesy of Dr. Stuart Jefferies, MSRC director, and Ms. Kathy Schulze, KJS Consulting)


I think in this case the real 'trick' relies on the use of adaptive optics. The technology has been around a while.. so I'm not sure what's new here.. maybe they've improved the algorithms used in processing.
Unfortunately unless you have some mythical adaptive optics lens (I wish.. :P ) I can't see it being much use for the average photographer.

More info on adaptive optics here: http://en.wikipedia.org/wiki/Adaptive_optics

Maybe I've missed something here though :? I'd be interested to see results if anyone can get that software working properly :)

But doresn't it say they use NO adaptive optics?

I think this is a case of taking imagery using optics with known distortion parameters and using software algothingies to remove or correct that distortion. It's a bit like profiling your lens on your D70 and having software to correct for all the aberrations.

If after reading the above anybody believes I know what I am talking about....then I gotcha! :lol: :lol: :lol:

It looks like they have the early beta release of the D4Xsi.
The upcoming Nikon with anti-blur protection...
