Breakthroughs...

Sure. You can do this easily in photoshop right now. Load an image. Save it out as a JPG. Then reload it and apply 10x noise. The details is now pixel for pixel. It's just not the right detail.

Or you could trace a person walking along a river. That black and white image may be far 'sharper' than the original. It's just not a funcitonal image.

Detail is frequency. Add noise to any signal and you can increase the frequency. Fractals try to extrapolate the 'signal' noise and all. So it adds in visual details that aren't necessarily 'motivated' by the original.

here's a breakthrough...

but one we won't see in commercial cameras for several years.

sounds cool though

from the page:

Thanks to this lucky mistake, a new breed of camera sensors that are cheaper, higher-resolution and have lower distortion could be on the horizon.

FYI here is the paper in Nature:

The correct, full content publication is as follows:

P3HTCBM doped with CdTe has QE (Quantum Efficiency) of 8000% at 350mm! Again, CMOS and CCD QE is usually around 50%, but there are ways to get it up to 90%.

Luckily, I know exactly how to get that working across all the color wavelengths. I worked out an idea to do this for another project. Red! Actually, this might suite another project I wanted to do, I wonder how had it would be to make our own sensors with this. I could make a medium format sensor to make it larger and easier.

eee.....what ? A 4 year old thread ?

Waaaaaayne! Why???
