Should we put blade covers around helis too? You know, just in case a kid decides to go jump near one...

Not trying to belittle the dangers, but something like this falling from the sky is a hazard regardless of little bits of plastic around the rotors...

You gotta face the issue at the root, pilot registration or licensing if necessary, etc.

snapa: Nice gimmick, too bad the IQ is sooo bad!

" If you were attempting to capture the same view with DSLR quality you would be looking at a hardware/software cost of $10,000 or more. "

That seems like a vast exaggeration... There's free open source software that can stitch great 360 degree panos *and* export them for VR use (and it's not a recent development).

As for capture, all you really need is a decent camera + FE/WA lens + tripod & pano setup (don't even need something as fancy as a Nodal Ninja, DIY-ish kits from someone like Hejnar/Sunway/Desmond will do for half the price).

That's maybe $3,000 in hardware if you absolutely must have a FF setup, way less otherwise (or if you buy some used/older gear). Could easily manage it for under a grand if you stick to crop bodies; including camera, tripod, pano hardware, etc.

Keith57: Interesting article. Kind of overlooking that 360 panos have been around for around 15years !!

What I would like to add is a note about composition. It's not that simple! Where you place the camera and at what time of the day is crucial for a good image. What works for stills won't necessarily be good for a 360 photosphere.

Also, some people still confuse the 360 distortion when viewing the final image with the lenses used to capture the scene. They are totally independent. You can use a fisheye and stich a few photos to render a full sphere, or you can shoot with a long telephoto and stitch 1000's of images to capture the same scene. All you end up with is different amounts of resolution.

The final file is usually a 2x1 rectangular image (called an equirectangular) and the software you use to view it on your headset or in your browser window determines the 'projection' and level of distortion or not.

Some examples here: www.fachen.org

Agreed, I think the (affordable) headsets add a whole new dimension tho... Regular 360 viewers seem to confuse people a lot as far as how to pan around (people that never played a FPS I guess :P ), the headset makes it more intuitive and immersive. I'd be curious to find out if there's a way to package and publish audio easily alongside the 360 VR panos, a song a spoken message or just ambient sound would add a whole 'nother dimension.

Maxfield_photo: Someone should tell the "European" Southern Observatory that Chile is in South America, they're liable to drown when they try to walk home from work.

It's conceived and funded by 15 or so European nations (at least until the UK packs up and leaves), built in Chile, to take advantage of the altitude and lack of air/light pollution I imagine.

In reply to:

tkbslc: I want to dismiss this as different from regular photography. But it is really just extreme wide angle photography. The same core principles of controlling lighting, what's in the frame and deciding where to stand all apply.

Seems like a rig with two cameras facing opposite directions and using fisheye lenses could recreate this. You might need to take one shot and then another with the rig rotated 90 degrees to fill in all the gaps, but shouldn't be too hard. And given what slightly older SLRs and Samyang Fisheye lenses sell for, it wouldn't be that expensive, either.

Two cameras wouldn't produce the best alignment unless they're tiny, plus it's pretty redundant gear-wise... The way I see most people doing it is FE/WA + a nodal slide for the best alignment possible (specially if the foreground is close), maybe a full on pano head if you wanna do the floor/nadir for the full 360 degrees...

Such a rig also allows you to take more shots, not just two, going really wide four would still suffice I think tho. Then use stuff like Hugin/krpano to process it... You can use the same setup for massive pano stitching too (regular wide 2D pano), going multi row etc... Useful if you can't go wide enough or just want a massive amount of res.

More labor intensive but it's gonna yield the best results until the day someone comes out with a dual mount mirrorless body. :p That or action cams scale up to 8K, which is gonna be the more seamless capture tool in the long run. Streetview on steroids...

Now that's something that I wouldn't mind seeing in VR...

Amazing either way.

One wouldn't necessarily had to wait for any tech to catch up to get 360 shots with better IQ, you can stitch that kinda shot together in post with stills from a DSLR or any decent camera and there's software that'll automate most of it and export the 360 for use with VR etc... The more painstaking part would actually be taking the shots for stitching (tripod, pano clamps, etc).

On article Sony Planar T* FE 50mm F1.4 ZA Sample Gallery (269 comments in total)
In reply to:

babart: For $1000 one can acquire a Sigma 50/1.4 plus the Sigma MC-11 adapter for Sony E mount. The MC-11 allows full auto control and works with many of the Art lenses.
If one happens to shoot Fuji, their 35/1.4 (50mm crop value) is $600. If one doesn't mind manual focus a Zeiss Contax 50/1.4 in mint condition can be had for $350. Like several others here I'm not certain I get the $2000 price tag.

Well the Sigma adapter isn't gonna give you the same AF as a native lens, not that I'm debating the pricing... But recent articles on AF quirks when using adapters make them all look like an iffy proposition if you care about AF at all.

In reply to:

PB47: This is off topic but I wish 43mm had become the standard kit lens instead of 50mm. There's a Luminous Landscape article about 40mm lenses that mentions an interview with Sally Mann where she says 40mm is "about right" (she mainly shot with an Olympus 40mm for years). I love the full frame images I've seen out of that Pentax 43mm. 43mm just seems like the sweet spot. Pentax nailed it. If only Canon would make a fast 43mm 1.8 STM. That's my dream lens. But only Pentax will do something that weird.

Think you mean the Panasonic 20mm 1.7... The 14mm was 2.5 (and even smaller), the 20mm is still one of my fave lenses. Would probably be my fave if it's AF wasn't useless for video.

On article Samsung launches first removable UFS memory cards (175 comments in total)
In reply to:

TrojMacReady: A sparkle of light regarding possible backwards compatibility concerns, since Samsung stated in a recent interview with Droid-Life:
"The new UFS cards are not compatible with the current microSD card socket. However, we have developed a socket design that can support both UFS cards and microSD cards. We are working with different partners in the industry on this integration for next-generation devices.”

Seems pretty likely, Sandisk used to have readers that would read both mSD & Sony's proprietary mini Memory Stick (M2 or something? Not to be confused with M.2)... Though I wouldn't expect to see such a thing on anything besides USB readers and mayyybe phones & high end tablets. Any other market, like cameras, would probably just wait until the tech is commonplace and wholly necessary... Most cameras still don't take advantage of the fastest SD cards anyway.

They'll get there eventually tho, might even see some dual slots designs like you see now for SD + XQD or SD + CFast.

In reply to:

estarkey: This is kinda ridiculous. What is this, the fourth new memory technology in around three years?

Dunno about proprietary formats, but this is being positioned as the clear replacement for eMMC & SD in consumer products, all the major players (WD/Sandisk, Toshiba, Hynix, Samsung, Micron/Lexar) are on board with it. AFAIK it's the only standard with industry wide support like that since SD/mSD, and CF before that.

I guess there's XQD too if you're in the pro niche, which was positioned as a CF/CFast replacement... Though it initially only had Sony/Sandisk/Nikon behind it. Any other format i can think of (Memory Stick etc) were just highly proprietary, the writing was on the wall if you bought into something like that.

In reply to:

Archiver: So, while we can't put these into standard microSD devices, future devices from Samsung will allow both UFS and microSD. Is that what is being said?

No, future devices from everyone will just transition to UFS, it's a new industry standard and not a Samsung thing. It'll probably take quite a few years for cameras to go near it tho.

Toselli: In my opinion a bad move from samsung, it reminds my sony of some years ago, who created memory stick and no one but sony used. There were no benefits and they were twice the price of an equivalent sd. The benefit here is speed, but in my opinion nothing that can't be done with a new sd/microsd release. In my opinion also speed is not essential, on a phone (where this size is used) we already have a fast system memory, and the microsd is used almost only for music, photos and videos, which have no benefits with a faster memory. On a camera also speed depends mainly from the buffer, unless you shoot really a lot of long bursts at 10 fps, but the cameras made to do this already have xqd!

Actually, phones are already using UFS storage... Most flagship phones migrated to it this year and last, eschewing the old eMMC standard which was closely related to SD & micro SD. It represented a big boost in internal storage performance... Obviously they're using non removable soldered-on UFS solutions, but it's essentially the same thing in a different package.

BfSkinner: Would this type of storage be usable as the actual "hard drive" in new, cheap PCs?
They would certainly take up nearly zero space!

Any 2.5" spinning hard drive obviously...

It's already used as the main drive inside phones and tablets over the last year or two... High end PC use much faster M.2 & PCI-E SSD which aren't much larger than a gumstick, but you'll likely see some adopt UFS (in non removable form, like phones) at the lower end of the market (think Surface rather than Surface Pro). The performance is relative to that of an older SATA SSD, still better than any 2.5" drive.

In reply to:

Dr_Jon: I read the White Paper but it didn't say anything that made me think it's a clever advancement of flash technology rather than a tweak to aid performance in the belief that's the thing consumers really want and will pay more for. I suspect Micro-SD may prove to be "just good enough" for most users so it'll have a hard life.

Dunno what white paper you claim you read, but UFS represents a significant departure in communication protocols from eMMC/SD... Increased command queuing, much lower latency, more channel parallelism for way more bandwidth headroom, etc etc.

On article 8K Helium Super 35mm sensor on the way from RED (85 comments in total)
In reply to:

noflashplease: I shudder to think about the computing resources required to actually edit uncompressed 8K video.

Something's gotta push computing power and storage solutions IMO, as a tech head I'm actually intrigued by it... Not much else (gaming aside, and storage is irrelevant for that) is really pushing those boundaries, and it's left a market limping on a faltering AMD and a somewhat complacent Intel (possibly NV too if AMD's GPU division keeps focusing on high volume business like consoles).

In reply to:

Neez: I don't think they should use chemical elements in the name, unless it's involved in the manufacturing process or something. Do they use helium to make this sensor?? Otherwise, it doesn't seem right to call it the Helium Sensor.

Like if i were to call a car, the Toyota Propane vehicle, people would be all kinds of confused.

The hard drives you use to archive 8K footage are likely filled with helium (as many high end drives now are), so there's that... :p

Your opinion is sorely misinformed, no offense, read some of the other comments or do some research... This is a new industry wide backed standard btw, not a Samsung exclusive.
