On article TwoEyes VR stereoscopic camera simulates human vision (52 comments in total)
In reply to:

Turbguy1: ALL of these stereoscopic "solutions" require that you hold your gaze level (parallel with the recording interaxial axis). NONE of these will not provide true stereo if you hold your gaze at a significant angle (tilt your head to your shoulders) because that would require an almost infinite amount of data for true stereo VR imaging of a REAL scene at those (and all other) angles of gaze.

There are some very good 3d 360 videos from gopro using their many camera device and yes, it gives you 3d in every direction pretty good. The stitching is a little rough on all of them, but the 3d is ok when you have a bunch of cameras to capture the video.

falconeyes: On the Kickstarter page, TwoEyes claims only them are doing 3D movie and Vuze does not. According to Vuze and early CES testers, Vuze does true 4k 3D VR 30fps video too.
Is this false advertizing?
After all, Vuze and TwoEyes do the same at the same price per camera and makes obsolete this kickstarter project.

Yeah, its baffling why they show all their competitors then get it totally wrong on what they can do. The Vuze looks superior in every way except maybe size and cost.

Either way, for a $250 price point, if this thing works well, it should be a really fun device, even if 3d is only straight ahead and behind. The vuze is $800, so they sort of aren't in the same category.

Simon Zeev: I love 3d but I am sorry that the TV companies doesn't make 3DTV anymore.
May be is to late for items like this one.
The last 6 years I shoot pictures almost only in 3d (stereo) and I am very sorry that 3d doesn't catch the market. People are to lazy to put on 3d glasses an view 3d moovies or pictures.

Sony still makes active 3d large tvs. They are pretty much the only active ones. There are several that make passive 3dtvs now. It is dying out though.

gleung: if the quality is decent, this will be interesting.. i got HTC Vive, and looking at shooting 3D VR options to capture my family, kids(imagine capturing your kids growing up in 3D so you can 'revisit' the moment later in vr). Currently thinking of getting a pair of GoPro Session to do the job, but if there's all-in-one product, it'll be great.

If you want just 3d video, you can get an older gopro dual hero and buy 2 refurb hero 3+black cameras and that is true 3d. Sony is practically the only maker of a 3d camera these days. The dev 50 is a bit pricey, but it works well. You can also get a Fuji 3d w3 which is great for still but not really that good for video. Sync is very important for 3d and these all will be in sync. I own them all.

steve ohlhaber: So, does this mean non interchangeable battery? This is really a camera for the non enthusiast.
- Water proofing at 33ft vs hero 4 which is over 100ft
- No improvement in 4k shooting
- No battery change? what
- Stabilizer yay, one positive
- gps - who cares
- post to the cloud - who cares

After the session failure I thought they understood that the session is for the masses, but they needed one for the more serious people. So, are they going to make a dive housing for this hero 5, or do you have to restrict your dives to 33ft. One button, great, what do I have to do, talk to it now. Is pushing a button too hard for most people. They went and screwed up their flagship. Unreal. How could they possibly think those were good ideas.

Awesome, so now the dive housing shoots through 2 pieces of plastic. You have the lens, then the plastic in the housing, then the plastic in the dive housing.

mpgxsvcd: The GoPro 5 Black will run circles around these cameras for $100 less. FAIL!

The Nikon only has electronic stabilization I am pretty sure, they said the x3000 has optical stab. So, I would say the gopro is better than Nikon 170, but the keymission 360 really is very different. Nothing much out there like that except crappy versions of that concept. This looks like the best all in 1 360 thing so far. Not cheap, but looks decent.

1.64x crop for 4k video????? you have to be kidding. What is the point. If you are into video - buy an APSC 4k camera and save some money.

Tal Shachar: Canon 80D is 24MP APSC sensor 1,200$
new Canon 5D mark IV is 30MP FF sensor 3,500$ (3 times then 80D)
so for video shooting Full HD or 20MP still pictures it seems that i'm getting the same size of pixels and quality in both cameras.
so the advantages of this new 5d mark IV camera is only if I shoot 4K video or 30MP still pictures. So i'm just getting larger pictures and larger video size.
I'm not getting better quality (larger pixels) in new camera compare to 80D.

and yes i'm aware of the internal GPS i'm getting in the 5D mark IV and some other few features. compare to the 240$ GP-E2 external GPS I would have to buy for the Canon 80D

If you cant tell or don't care about the difference between APSC and FF, you absolutely should get the 80D. Their prices did seem to take a hike up with the mark 3, so this was no surprise at all coming in at $3500. I think many people bailed on them already for Sony over price alone. I would have but the canon glass really is very good on the high end. I can use adapters on the Sony. I would like a mirrorless FF canon, but they seem to be 7 years behind on all these crazy new inventions the kids are into these days.

I wonder what a correctly exposed frame of just the jet plume looks like. The engine should not even be visible with the right exposure.

I will buy a 360 camera because I have to choose a forward or backward view right now for surfing video. It would be nice to not have to choose. I am waiting to see if gopro has some release soon as they are overdue. Outside of a few cases, I would not bother with 360, but I will use one a lot if its relatively small like the gopro.

In reply to:

noisephotographer: I wonder whether the decision of 28mm instead of 35mm is good in terms of image quality. The field of view of a 35mm lens would contain the field of view of four 70mm lenses. That's the concept how they improve the images computationally. A 35mm image would have been calculated via the data of five 35mm images and four 70mm images (each corner) + one 70mm image for the centre of the image. But the field of view of a 28 mm lens would contain the field of view of more than six(!) 70mm lenses. So I don't know how they want to do this.

I would guess they knock that 70mm down to a 56mm. But, they cant get virtual focus and aperture if they use all the lenses to cover 1 space, they need to vary some by aperture and focus to allow the correction in post. Maybe the blur is really one wide angle, cause the blur isn't a high res thing.

If they initially thought people want 35-150mm focal length, they already don't get it.

In reply to:

PixelJ: I wish these action camera companies would offer swapable lenses for 90 degree or 80 degree fields of view.

They sort of do. Gopro uses a threaded lens mount. If you replace it with a 5.4mm lens you get 30mm relative field of view. I have swapped a couple out, but its not something you can do quickly.

A "real" camera does not belong on a surfboard. It has to be small. Its ideal by design. And yes, I want a fisheye lens on it because I need a wide field of view AND I don't want to pay $500 just for the waterproof housing.

GCHYBA: How is this better than a GoPro?
I'm just curious, the specs look similar, but the GoPro has all these mounts and stuff already out there.
Someone educate me please?

Its hard to tell what the res and framerate actually are. No great detail on their site.

The killer here is gopro can do 2.7k at 60fps. That is an important setting because you can reduce the image to 1080 and gain some of the sharpness in the downsample and still be at 60fps. This camera can only do it to 30fps.

If they are using a sony sensor now, it really may be solid competition to the gopro. I am doing 3d with the 3+black gopro, and nobody does that. Also the gopro has the ability to do external mics and displays and offers a bunch of different FPS and resolution AND lens FOV selections. I see all those features bleeding into the knockoffs. I really debate getting a knockoff now.

Gopro delayed their new flagship hero. I just hope they don't make it in the session form factor. They have indicated it will be that shape and I do not like the lens in front of the lens concept. I want it in a waterproof case, or the raw lens, not some acrylic thing always in front of the lens. Not to mention ALL my cases wont work then.
