4x the photons headed your way.

Quantum Dot sensor breakthrough (article link here).

This article is about a new quantum dot film that is easily laminated to a standard CMOS type chip and raises the silicon photon capture rate from 25% to 95%. No new factories required, only industry standard manufacturing techniques. They are starting with small cameraphone type sensors, but it will only take a few years to reach the big boys if it works as promised.

Isn't it great to know RED modularity and vendor upgrade policies are actually on your side for things like this when they arrive?

This is, what, the fifth time this has been posted here?

Cool tech though.

assuming there still the accracey in being able to read the voltage of the photo sight. that would turn the 15stop monstro in to a 17stop monstro. just on the 4x increase in light.

when we no longer have a latitude war, or a resolution war, what will be next. how RAW can you go? and how fast i guess. and when digital outperforms film, will it then stop being the main format? interesting times

It increases sensitivity and so useable dynamic range, which will help low light shooting a lot, but it doesn't increase absolute dynamic range as such.

 

[Jeff Kilgroe]

Increased sensitivity does not equal increased dynamic range. And the 4X efficiency claim does not really mean a whole lot since they're comparing with older sensor designs that have been on the market for a while. Many new sensors are far more efficient. That said, I think quantum dots hold a lot of promise for both sensor and display technologies coming up, but it's a bit difficult to see exactly where these benefits lie until this is applied to practical applications. More than sensitivity gains, what looks more promising to me is that a quantum dot matrix could theoretically eliminate the need for color filter arrays such as bayer patterns.

Increased sensitivity does not equal increased dynamic range...

That's what I meant by useable dynamic range, as distinct from absolute dynamic range which doesn't change with this technology.

Increased sensitivity will increase signal to noise ratio in the shadows. Cleaner shadows mean more of the existing dynamic range is useable without noise being an issue.

How would that work?
