retcon··on Clinically clean lenses are destroying what makes cameras special
The latest cine sensor ADC designs are playing with the read line amplification now that stacked readout reduces input loss.

Edit: Nikon has been onto this (and silent) for much longer.

retcon··on Clinically clean lenses are destroying what makes cameras special
Spot on about the new picture being a stream.

"Super resolution" may be the marketing term to search for to investigate your interest. However sequential image composite decononvolution hasn't solved for usually desired out of focus transition effects commonly hand waved as " bokeh" because the important contrast gradient limit of the Airy Disc is convolution.

Accelerometers are appearing even in the lowest budget cinema cameras whilst ARRI, the de facto market leader who used to be the left field upstart (finishing The Bridge Over The River Kwai, critically being inexpensive light and ergonomic of which only ergonomic is arguably retained by contemporary boxes) has just gotten around to putting one in a smaller sensor camera that costs six times the bigger sensor competition. (I'll ignore the 3:2 vs 4:3 ratio of the newest ARRI is wonderful for anamorphic squeeze and utterly wasted for spherical shooting.. and ignore RED offering very usable ratio comprises.

Edit: disc not discussion

retcon··on Clinically clean lenses are destroying what makes cameras special
Article ignores you can take 30fps of 89MP stills for USD$5,995 list using a BMD, and for less than well heeled hobbyists spend on DSLRs purchase the lenses to taste. [0]

People are designing brand new lenses with well defined abberative character. Orion is a new company who are enjoying mainstream Hollywood adoption. Key scenes in John Wick 2 are taken with Orions. The car park opening action in particular setting up the movie. (Yes, I justified watching John Wick 2 for the optical research. Twice..)

Cooke, the British lens maker infamous for "The Cooke Look" precisely because they hand calculated [0.5] attractive and until very recently [considered] minimal distortion into consistency across their range, are selling right now brand new lenses which retain a considerably consistent amount of that same character whilst hammering undesirable optical traits into negligible measures. Remember that these pictures are being enlarged. (projected) tens of feet across in your nearest theater. Moving vs still pictures do conceal imperfections, but everyone making pictures with these are staring at freeze frames in the DIT and post on equal or better projection for extended periods of time, and distractingly flawed taking optics would simply be eschewed today except possibly for effects cut scenes.

Contrary to the articles self serving and probably just ignorant statement, the lens making Zeiss Consumer unit [2] is in fine health.

However they're making progress in cinema lenses, because this more immediately pays for and nurtues the necessary R&D that's become expensive or impossible to match or follow Sony, Nikon, Canon and Fujinon.

Rather than lament fictional losses of the strongest historical names (I'd be mad as hell if my company was misrepresented in this way) we are gearing up in a renaissance period for optical designs for all applications including enthusiast photography. I have to stop here because the next item on this agenda is manufacturing tolerances and capacity, which caused by increasing resolution has been pushing costs and logistics into divorce territory from the industry of merely ten years ago. That separation is probably underlying so many unfounded and hysterical outbursts posing as nostalgia such as this article.

[0] The BMD is a 12K / 89MP S35/ APS-C sensor for which the highest quality lenses can be obtained for the price of as low as a couple of eg Canon 50/1.0 examples (being just such a lens as draws a very attractive picture with far from modern corrections).

[1] Cooke never seems to have been forthcoming about automated design aides, however the human element and its degree in designs isn't unique even for the hyper corrected Sony and Nikon glass recently launched.

[2] maybe it's revealing that Zeiss denotes $20,000+ lenses as consumer products, but we're informed by their semiconductor division. This price isn't a outlier in any specialist photography field but the performance of this lens currently is a outlier.

retcon··on SOC2: The screenshots will continue until security improves
Genuine question: is consulting for compliance exclusively the possibility for big four type firms,or can't we do this at (traditional not scale up) start-up style? I'd buy your pre money common stock off your comment alone and the similar applies to numerous others I keep reading here.
retcon··on Why isn't the internet more fun and weird? (2019)
I've done a penance ^h^h career in advertising ,[0] and I left because advertising sold out. Advertising and commercial art/advertising/deductible graphics used to nurture the most amazing arrays of cultural perpetual moonlighting geniuses. Now that went down the first conversion funnel long ago. We're not even a number were just amorphous $rnd now.

[0]Computational advertising for print in the very early nineties...)

Edit: a last gasp website I absolutely considered Sui Generis and was invaluable in the graphics world was Drawn.ca . I'd be immensely grateful to hear of any mirrors or archive.

retcon··on Documents reveal McKinsey's role increasing opioid sales until 2019
But the entire point of OxyContin is to induce opioid withdrawals every single day by lying claiming that the release formula is effective for 12 hours, but making it cease dosing at 8 hours. Regular removal of opioid availability from a patient has the pernicious effect of creating a excessively of desire for a normalizing dose but removing all base levels to zero puts the brain and body through another cycle of low and high experience and so OxyContin makes immediate junkies out of everyone unfortunate enough to be prescribed.

I think the OP just coined the phrase "Tesla Privilege" for egregious acts of attempted vehicular manslaughter...

Edit because humor isn't the done thing here, or for the subject, the quote is "a privileged system of trust to enable learning." But that would be less pithy.

>It is when you’re a software company and the marginal cost of the goods is zero.

$600mm annual sales and marketing isn't cost of goods but the method of accounting that I subscribe to includes such costs as a fundamental cost of production delivery.

retcon··on Three Arrows Capital has defaulted on a loan worth more than $670M
Default means that you are or have been technically deemed incapable of making any further payments. This includes repaying the principal outstanding.

You're confusing any potential amount ultimately recoverable in insolvency with some kind of imaginary ex gratia payment by a management of a imaginary going concern which absolutely doesn't exist in Ch.12. Its chapter12 in the circumstances conceived.

retcon··on Where did the long tail go?

retcon··on ‘Blade Runner’ at 40
Whilst freak examples of effective period Japanese Anglo Saxon industrial cooperation have been known, [0] surely British Leyland is stretching too far. In fact BL's board did claim to Thatcher that they were going to build a new small family car with Honda about this time, but management only wanted more money to avoid hassle with the shop stewards.

retcon··on Nikon Z9 Disassembly and Teardown
I've been channelling Thom Hogan who I've been reading for over 25 years. Thom is the most rational (and frequently only sensible) publicly available voice in the technical aspects of photography. Thom also worked for Osborne Computer..

Edit: https://bythom.com. by the looks of things about everyone here ought to go catch up with Thom's writings ;)

retcon··on Nikon Z9 Disassembly and Teardown
Sony's A1 became available almost half a pro body (4yr/2, actually nearer1.5y given pre production) than any other top level mirrorless cameras. This plus very aggressive selling support services to the agencies(which are a negligible number of pros globally especially in the states) gave Sony the home advantage Japanese pride fully deserved. As is self evident the performance level available from the A1 is too good to pass, especially when it's the only show in town.

But the A1 is the first professionally usable Sony period. Tokyo was Act1, Scene 1.

retcon··on Nikon Z9 Disassembly and Teardown
Reflex mirror assemblies require physical damping that smaller bodies seriously struggle with. Engineering reasons trump Japanese desire for smaller cameras;)
retcon··on Nikon Z9 Disassembly and Teardown
I think that some users are actually expecting their EVFs to magically eliminate motion blur when panning. Have you tried the Z9 since the firmware brought faster refresh? I'm surprised you are passing the Z9 given it appears you shoot heterogeneous. That said I'm seriously looking at D6/120-300_2.8 for the similar reasons, but I think my reasons might be a bit more distilled.

Heaven forefend that Nikon engineering chose the card format to match (exceed with headroom) the required transfer rate ;)
retcon··on Nikon Z9 Disassembly and Teardown
Do you mean tune focus as in lens back focus calibration, or fine tuning your focus point in the desired picture? If the latter you're doing it wrong ;)

These are customer runs of proprietary designs which extends to the filter pack, micro lens array and potentially the stacked data take off layout, but the core is all untouched Sony.

The far more important question is why our authorities have been totally willing to subject potentially countless of our citizens to arbitrary and unlawful imprisonment?

Every games for fairly obvious reasons has been shagtastic.

We shouldn't go.

Edit"countless" because you might not need to count just assume everyone single will be arrested. I don't dare look up their laws pertaining to LGBTQ+ folks.

Edit2: add in installed NSO and other deep inspection wares plus terrorist motivations internally against their state (for much the same objections natch) and we're going through'72 again.

retcon··on Ask HN: In these uncertain times, how do you handle anxiousness
Go running.

Then read Shoe Dog by Phil Knight and go running again.

If you have gotten unfit the book will have you laughing with the guy at all he had thrown at him and then you'll find that you get over yourself the next run you take.

Any other books that people know about this positive?

I've been totally kicked up my rear by Knight's book, in the best possible way.

retcon··on Why am I no longer qualified to be a Brex customer?
>PR mess on your hands

The idea that this doesn't require face to face handling simply chills me to the bone. Is this how we're preparing for the worst economy in fifty years?

edit: PR used to begin with word of mouth. Just because we're online doesn't mean you can sh*post excuses and be done.

retcon··on Why am I no longer qualified to be a Brex customer?
>I don’t understand why you’re still not laying out the new criteria for being a Brex customer?

In a bygone era I'd have suggested that shame came into it.

It's because you can't convince anyone you're competent whilst acting up like this.

retcon··on Why am I no longer qualified to be a Brex customer?
What were your reasons for attempting to sell your services to smaller businesses in the first place?

You have made decisions capable of inflicting tremendous pain on entirely innocent people eg employees.

How are you to be believed that you will not randomly hurt more people?

Buddy this isn't PR this is proving you're not a dangerous child entirely before you defend your job.

retcon··on Why Rust is a great choice for startups
>compute is cheap. Go with what you know.

sorry for picking on your comment in this generic fashion but I am critical of these memes not your observations:

Compute Is Cheap(where Gustafson Bariss is true)

https://en.m.wikipedia.org/wiki/Gustafson%27s_law

Going with what you already know is fine for knocking out the cobwebs and getting into a space. But most generally certainly in my experience I've never done anything to completion I knew at the beginning.

retcon··on Why Rust is a great choice for startups
1 may be better asked as what aspects of your team understanding of any considered language apply to your problem space. How well can you port that knowledge to another model of expression.

2 is fine. the more significant question is often do you want to work with that talent pool and does the pool tell you more about the costs structure of your sector against which information you may prefer to tack against the prevailing winds and even more patiently attempt to trade actual equity for deep abilities and stuff what language is chosen if your stock has value.

I don't understand how much attention individual languages receive. Plural understanding across your team and ability to transcribe the code into valid parseable docs against which APIs are easily written, is paramount in my mind. Corollary to my incredulity I have often thought that you emphasize the codebase language and dialects only to find you fuelled holy wars and dissipated your technical mission values. Which is disastrous for hiring the kind of colleagues we get up in the morning and forget about industry grief to share increasingly awful spaces with.
