Apparently, a Google scientist (whatever that is) has invented light efficient photography

Sounds analogous to HDR, but for DoF rather than dynamic range.

Sounds to me like a combination of HDR and focus stacking. Not sure how it would work with a rapidly moving object.

If I understand correctly the user would think they were taking a photo at f8.0 (but the camera would really take several photos at a wider aperture to simulate that) and it's all done behind-the-scenes in software. I can imagine it being used in compacts, phones etc, wonder if it would eventually make its way into SLRs.

It's a new science discipline. Rather than thinking for yourself, you just pop your question into Google.

Have read it twice and simply don't see what is "light efficient" about it. Interesting otherwise, just a refinement of the sort of thing we already do routinely with CombineZP.

And yet another example of the journo-babble of AP sub-editors. A perfectly respectable description of the guy as a Google software engineer (Google employs several thousand of them, of which my son was one until he left to set up his own dot.com startup in Silicon Valley) into a "Google Scientist" which does, I agree, sound faintly comical.

Following their link, it appears the idea comes from Hasinoff and Kutulakos at the University of Toronto, published in an IEEE journal, with some impressively horrible equations for the mathematically inclined. But there doesn't seem to be a connection with Google except you can find it through Google ?

I suppose the idea is, they can control the camera well enough to take rapid multiple exposures, and get better results than using a small aperture. Whether it would be worth doing in practice might be another matter.

Another one for people who collect strange headlines.
