Larger pixels do not 'collect more light' in real camera systems
Yes, they do. But skipping past some flawed analysis and misunderstanding,
Summary:The only way to get more photons to the sensor is to make the physical aperture (D) bigger, or to increase exposure time, or increase the scene lighting.
Actually, yes, I'd agree.
Photons : Sensor Ratio at fixed aperture, fixed exposure and fixed lighting is itself fixed for a given sensor size, no matter how many pixels there are.
Now, do the maths. If that ratio is fixed then how many photons hit each pixel if the sensor has 18 megapixels, as compared to the same size sensor having only 3 megapixels.
Larger pixels DO "collect" more light because they have greater surface area and a greater share of the total light hitting the sensor. The sensor as a whole has a fixed amount of light hitting it, but no longer has to split that light between as many pixels.
This means better quality interpretation of the light.
since there is NO practical effect on real camera systems, you might as well use a small sensor, since digital sensor pixel pitches are fine enough to support even smaller sensors than film.
The issue isn't how finely you can split the light to make 18 million readings. It's how accurate those readings are. When shooting using the illumination caused by the glow of a incense stick (as described in the article) you need some pretty sensitive light detection to avoid losing your entire image in noise.
The larger pixels give you that sensitive light detection, by capturing more light per pixel for a given sensor size.
The other way. You'd be able to use a quicker shutter speed due to the increased light capture.
If you want long exposure times, just fit a neutral density filter.
I'm interested in its dynamic range, and whether that's better or worse, but the main point of the sensor is the ability to capture usable images in near darkness. I have several good uses for that!
Don't forget the benefits in physical camera size. I shoot Micro Four-Thirds so that my camera with lens attached fits into a coat pocket. People just don't generally want to lug around a heavy medium format camera with humungous lenses.
The irony is that it's a step back to ye olde times (about a decade ago) in digital SLR pixel counts.
The difference is that they're using modern sensor technology, which means it's a fantastic idea for non-professional video (and possibly as a second-unit camera for some pro stuff). It'll even take stunning still photographs; they just wont look so great printed above around A4 size.
Except that 35mm isn't 'added for backwards compatibility'. It's still a viable format, it's still in use, it matches a standard professional digital camera sensor size and it's a common reference point across the industry.
Then there's
a 35mm lens
A 35mm lens has a focal length of 35mm. That has absolutely no bearing on sensor size; you can put a 35mm lens in front of a mobile phone sensor or in front of a Leica S2. It's still a 35mm lens.
Of course, you can also put a 35mm (35mm equivalent) lens in front of any sensor. On a mobile phone that's going to be about 4mm in focal length and on a Red medium format could be 50-60mm. Suddenly we're seeing the benefit of using the 35mm reference point, even though we've got a magnitude of difference between actual focal length, they're all giving comparable field of view.
Depth of field, that's a different story. The larger your CCD the narrower your depth of field at 35mm equiv.

While I was using Napster I was buying a least two albums a month. Prior to using Napster I was buying at most two albums a year.
Since Napster got shut down, I haven't bought any new music. Fuck the music industry, it didn't want my money or it wouldn't have destroyed the vehicle that generated such great sales.
So what you are saying is that music should be free and artists should go without health care.
No, only artists that let their representatives sue their customers. Fuck 'em.
Well, for a start they all demonstrate inherent stupidity anyway: They trust abusive manipulative men to tell them the truth despite the extensive evidence that they're corrupt and lying.
Secondly, having emotional detachment from the process means that I'm better able to analyse it logically and determine actual impacts.
Finally, I'm arrogant enough to declare a billion people to be wrong. You have a problem with that?:)
No, you misunderstand. Maybe about a billion _think_ it's important, but frankly it's all much the same to them: They get a new pope. He oppresses them.
The only people it really matters to are the cardinals. Will it be someone that'll give them a cushy job, boost their own prestige/power, massage their ego, give them blowjobs, or just some other megalomaniac intent on fucking over a billion people.
You forgot to even mention the inherent bribery, corruption and other politics between the cardinals themselves.
Lets face it, a bunch of malicious corrupt people electing someone to run a malicious, corrupt and destructive organisation isn't an exemplar for any electoral system.
Far more interestingly: If they can do this on an android tablet, they can do it on an android phone. That's even more discrete, and quite probably just as usable.
Excellent way of learning data analysis and visualisation techniques. He'll have gained personally and as a by-product has created an interesting resource for others.
Not sure that's a waste of time or resources at all, especially if you start factoring in the enjoyment the whole exercise probably provided to him.
Sorry, "an estimated 300 mile range"? When it's sub-zero temperatures outside, I'm driving fast and I'm accelerating hard on country lanes?
Add in a potential road closure (accidents do happen), traffic jams, heavy traffic even when moving.. I'm betting I could use up that estimated range in half that, probably less.
On a 110 mile drive, that leaves me with fuck-all contingency. No. I don't want to drive at 60 with the heating off, the cruise control on, taking forever to get up to speed, all to eke out the power reserves in the hopes I'll get to my destination. For $40,000 I can buy a fuck of a lot of diesel for my current car which has none of those problems.
While theoretically you're correct, when the FSA demand a report two days ago in a format they only published today, the Finance team aren't going to fuck around writing queries. They're going to grab 68 different spreadsheets and pull numbers from all of them.
I have satnav directions disabled, so its not supporting my journey, it's merely notifying me of adverse road conditions.
I don't recall claiming superiority either, just confusion that some people might need it to mention a petrol station they drive past regularly and that's in sight of the road on which they're driving.
Do you know many people that program their journeys using forty mile segments between various potential stopping points?
Slashdot Mirror
recording when a pixel has received a certain amount of light, then resetting it and in effect restarting the exposure
Isn't that a bit obvious? Now that someone's actually had the idea and made it work ;)

So what if they can show damages? That doesn't make it actionable.
Nice response :)
Sadly I lack the access to reject at the SMTP server, it's a post-receipt validation/rejection.
I'm not entirely convinced by the backscatter argument though but I'm too tired to think it through so I'll take your word on it.
I check all headers - a lot of spam isn't addressed directly to you.

Do you have any idea how much money the organisations represented by the RIAA generate through exploitation of artists and customers?
Hiding behind an industry organisation merely gives us a single label to describe the whole bunch of them.
You misunderstand the nature of music. Nobody owns it.
Some people like to think that they do, but they're merely enforcing an artificial monopoly, but the music lives anyway.
I have music in my head. You can't hear it, but you can watch as I dance to it if you like.
he killed (terminated) the upload
Actually his words were "I terminated someone". It appears that it wasn't the upload he killed.
A tad harsh perhaps, but people shouldn't saturate your upstream.
You're talking shit.

The road closures, no, but they do happen and I really don't want to get stuck in the middle of Staffordshire because my car's got no power.
The rest of it? How the fuck do you think I've been getting to work all year?
Sure, ok.
Skydiving! Excellent fun. Or better yet, base jumping. That's a real rush.
Or did you want us to wrap ourselves in cotton wool and never leave the house?
Life is dangerous. 100% fatality rate up to now, so just get over it already.
