See, if he were Richard Prince (who does exactly the same sh*t, but is far better connected and monetized), he'd be charging hundreds of thousands apiece for it and they'd be headed for Guggenheim - any controversy only adding to the appeal. Prince's Wikipedia page has this gem: "His mini-museum, Second House, purchased by the Guggenheim Museum, was struck by lightning and burned down shortly after the museum purchased the House"

cosinaphile: while 10 k per eye sounds like crazy overkill during the actual immersive experience
appx what would be the resolution per eye as a viewer looked round the virtual environment ?

anyone know? { appx]

Supposedly, 576 megapixels (if you only look around within 90 degree or so forward field of vision, i.e. 45 degrees left or right or up or down). The "looking around" part is important, because the resolution is crazy high only in one spot on the eye's retina, but our brains are really good at aiming those spots covering all the important parts in the scene. So, if the scene is to be convincing, it should be that sharp everywhere. And if we want the whole sphere, not just the forward quadrant, well, that's 6 x 576 megapixels.

Somebody said "wait a minute, those other clowns got $34.7M for Light L16 https://en.wikipedia.org/wiki/Light_(company) - what can we do that's more absurd for more $$ ?"

Alec: I think, in exchange for a greater and reasonable freedom of flying in the populated areas, larger drones (1kg+ / 1km+) def. should be able to be "pulled over" by police, as in, directed to land next to the police car or something, per signal from police.

Because suggesting an absurd way of going about it doesn't nullify the underlying issue. And the issue is, on the one hand, you can cause a life-altering or lethal injury with a drone, or cause expensive damage, just like you can with a scooter or whatever. And on the other hand, just like scooters, drones can be tremendously fun and useful.

So it's quite hard and incredibly important to get the balance right. And it won't ever be perfect - there will always be a knucklehead who'll mow down a family on a picnic, and there will always be a cinema masterpiece by an unknown director who'll stay unknown because she/he could never get a permit to shoot what they wanted where they wanted and the way they wanted.

Why not also make everyone look modern? Give them all hipster beards and suspenders. And torn jeans for the ladies, regardless of age.

RolliPoli: I find this very objectionable. Will Rembrandt's etchings be colorized next? How about a bit more saturation in DaVinci's paintings and what about all his black on white pencil drawings? I really can not, without getting profane, express how much I loath the whole idea of 'colorizing' black and white photographs and movies. This crap is a full body exercise in bad judgement and even worse taste. There should be jail time for doing this kind of stuff. ;/ Thank God the photographers who shot the original pictures are long dead and unable to take reprisals on the feckless drones who have done this drek.

Don't you want to see Yosemite in technicolor??
Also we should edit old films for political correctness and old newspapers describing events inaccurately.

I accidentally knocked the cup over, and the results were clearly NOT low-dispersion. False advertising!

On article Vimeo adds support for 8K 10-bit HDR videos (35 comments in total)
In reply to:

Life recorder: ....and the gear heads here will rave about how awesome that 8k video looks on their 2.5K and 4k monitors. Forget the content... You must zoom in to 100% to fully appreciate video (and stills)!

8K is a must for 180 degree / 360 degree videos because 8K is the entire sphere, and hence panning within it is realistically 720p at best. I've a 4K 360 deg camera, and the results are clearly resolution constrained.

BobORama: Cool animation. Wrong conclusion. Obviously if someone with a sub $1000 drone can shutdown an airport, endanger passengers by piling up planes which increases the potential for disaster, its not irresponsible drone operators we need to worry about - its malicious drone operators. A mechanical means is needed as it is easy to "enhance" consumer grade drones to operate entirely autonomously.

Many drones are built of high-strength composites and alloys, and contain high energy density LiIon / LiPo batteries known to ignite or explode when dropped let alone smashed. So when a drone is sucked into a jet engine, it can cause damage far in excess of what a bird would.

Alec: remember, the cloud is just somebody else's computer

LOL no wifey here, only wifi, but IoT's reliance on perimeter security, such as the router's firewall (which is often limited or misconfigured) is a valid point.

Google's cloud (docs) had 2 issues recently, both due to bugs, and if Google is slipping up, what can we expect from others? I suggest moving to private cloud - basically a NAS (or a pair, with the 2nd one in another location & synced) by QNAP or Synology or self-built with Linux. That ecosystem is maturing where we can have most cloud functions using hardware that WE own.

ovlov: Bankruptcy is just around the corner. Will it be Canon or Sony that buys what's left of Nikon?

Nikoncanonfan: you may be right about the perception, but they used to say the EXACT same thing about things made in Japan a few decades in the past, and the US electronic and car industries had paid the price for failing to see beyond that dismissive stereotype.

I view this closure as a bad sign for Nikon, because a factory (including a functional team running it) is normally a long term investment. For short term needs, contract manufacturing is used; if an own factory is closed instead of being refitted for a different product, it's because the firm is losing ground overall (and doesn't see regaining it) - not just for the type of product made at that factory.

otto k: So same as the previous version?

Fair enough, Ebrahim, but how do we quantify "Full-frame mode is improved"? I like the idea of improvement, but it's not the same as us being shown it side by side old vs new, and measuring it.

If I'm to stick with a camera for 5 years or so (minimizing landfill and wallet drain), if a company is telling me they think those new 8 bits will be good enough on this level camera for the next 5 years, because they're much improved over the last model's 8 bits, it's understandable to want to know improved by how much exactly, don't you think?

But where can I buy the same random startup's opinion of what my creativity ought to look like, in a digital form? Maybe a Photoshop layer that I can't take off after purchase?

I remember the hipster craze of shooting through the viewfinders of flea-market TLR's to get that olde looke - needless to say, every one of the trailblazing lemmings partaking in the fad would summarily dismiss the idea that "this, too, shall pass".

No, see, the old one was 8 bits, but the new one is EIGHT BITS!! Now we all march to the store to upgrade.

Franz Weber: This is what I can not understand: when the image sensor has a aspect ratio of 16:9 why do they use circular lenses? Wouldn’t it be better to use oval lenses in order to safe weight and cost?

Enginel You're 100% correct. My post was TMI as it was so I "simplified" that one off. Thanks for reading mindfully! :)

1. Great question
2. All the surfaces still have to have the spherical surfaces (or aspherical, but with rotational symmetry). Equipment to fabricate those is built for round lens blanks and finished products.
3. Out of focus highlights / bokeh, on wide-aperture lenses, will reflect the shape of the elements. Canon's 85/1.2 has one side flat due to how it mounts, and it shows up in some shots. Some of the newest f/1.2 and faster lenses coming from China now, suffer from almond-shaped highlights off-axis (too-small front elements, like looking through a paper towel core tube off-axis).
4. BUT you're correct, and esp on a drone it would have saved weight to shave off top and bottom from at least the front element group (improving flight time + range + gimbal response). But factors #2 and 3 are strong enough they'd even not done it with video cam lenses they were taking to the Moon - while the band-aids they did count. But-but, on 70mm film lenses it's done sometimes.

Androole: What is a tripod "made specifically for a Sony Alpha camera"?

It seems to be the only thing that is really camera specific is a plate designed to integrate with the body to prevent rotation, e.g. RRS plates.

For video, Manfrotto do make all manner of remote controllers. It is possible they want to get more into follow focus (high precision remote manual focus servo) game yet utilize camera's native focusing motors. It can be lighting (still or motion picture) that integrates with the camera's metering. Camera-hugging connectors that don't obscure the ports and batteries on current and planned (meaning under NDA) camera body designs.
