I'll grant you that sometimes there's just such a cool tech that you gotta hammer your head against the wall until you find something worth using it for. And sometimes maybe that creates something awesome (though I can't conj

The central problem in this entire debate is two groups talking past each other. The skeptics say "what is it for?" expecting a detailed answer, and the response from crypto enthusiasts is vague and high level; most of what I hear

The primary difference is that basic research is conducted with everyone's money -- mostly via grants, and a lot of it in the US underwritten by the federal government -- for everyone's benefit. Even the venture capital industry i

When has "market cap" been a measure of a currency? This is indicative of the logical fallacy so common in these debates, conflating "store of value" with "useful mechanism for transactions." It's a Ponzi

Honestly? I think it's similar to a lot of pop-business constructions. Post hoc, and it sounds insightful enough to inspire pattern matching, but doesn't actually have any real explanatory power. Anecdotally, I have heard people a

I believe this characterization fails to engage with what money actually is and does. It sounds good in print but fails in practice. Except for bitcoin's current "monetary" uses, like money laundering and tax evasion.

I've yet to see a "pro" for blockchain or NFTs that doesn't conform to the characterization you're trying to dispute. Care to offer one? I'm eager to learn.

I agree with you about how ugly the split screen effect is, but that's not strictly a camera issue -- you can sync strobes to your genlock signal. That reflects a production choice not a camera choice. The quality of global shutter cam

Don't do it. Cameras and lenses are a low margin, high labor industry. Professionals are exceptionally picky about their gear, so you need skilled technicians working hard to keep your gear in top shape, and the prices are very low. Th

I believe it's the other way around: Kubrick got a version of the NASA lens modified to accept a Mitchell mount so he could put it on a 35mm motion film camera. He only used it for the candlelight scene because he had to remove the spi

The lenses are expensive because they're made to very exacting standards but also they're a low volume product line. A cinema lens is hand-assembled from hundreds of components that must be aligned to extremely fine precision, wit

The signal is typically bandlimited by hardware — the optics and sensor. When it's not, you get weird effects, though that's rare because cameras have optical low pass filters to avoid this. When they don't, like the Canon 5D

Note, inflation also hurts those on fixed income — people whose income is set at a fixed rate, like pensioners or retirees collecting social security.

This derives from false pretenses, the US government can’t inflate away its debt; it gets rolled over and inflation expectations get baked into interest rates paid on debt (US treasuries are sold at auction). Governments that borrow in thei

The actual representation is using voxels to index a spherical harmonic coding of scene detail (I think), and that includes transparency so the novel view synthesis accretes light along the ray length. This lets it represent transparency an

Per the paper it's not quite real time (15 fps), and they suggest converting to a different representation (PlenOctrees) for real time. But yes, it's far more realistic than your simple mesh-and-texture; the video shows it handles

Yes, scatters it back out — that light does not enter the pupil or contribute to what that person sees (save probably a vanishingly small amount that is re-scattered in the cornea, which is totally de minimus).

As other comments have pointed out, this article is inaccurate — particularly about root causes. It's frustrating in part because it is so easy to tell it's not true: look at anything "blue" and notice that it's not

I don't think "remixing source images" is a fair characterization of this research. Finding pixel-accurate synthetic images is actually super hard. That said, yes, it's odd they're posing this as a way to extend gam

Re: Lytro, I gave them that precise advice back in ~2008, and I believe they had already talked about it. Nearly 10 years later, their cinema camera boasted 'lens emulation' but I'm not personally convinced it emulated bokeh

That's especially effective in a pressure cooker, where the elevated pressure and increased temperature allows the Maillard reaction to proceed in water phase. But be careful; I've noticed that if you use too much baking soda, you

Please see my response to Jacques, above. It's a partial rebuttal to the blog, because the blog is... in many cases "not even wrong," but it is long.

Fair enough. It would take a really long time to make a point by point rebuttal, but here are a few: Phase detection is not the same thing at plenoptic; the article implies that phase detection operates in the same way as a microlens array.

For what it's worth, film also suffers from reciprocity failure (nonlinear response at extended exposure times with low flux). Some things were never easy.
