4K3D Photography: What does it mean ? 4K3D Photography is a kind of virtual reality by ultra realistic imaging.
- Resolution: dual 3840 x 2160 native pixels (at least) for the final 3D image
- Real stereo imaging using 2 identical lenses and 2 identical sensors (preferably professional gear), orthostereo or hyperstereo
- Format: landscape format 16:9 ratio (genuine or crop)
4K3D-Photography is my designation to the ultimate technology to make use of every pixel of leading edge 4K/UHD-3D-TV display capabilities and the extraordinary imaging results. With the construction of a portable 3D-camera using 2 Nikon D300 on a rig and just one-cable synchronization I was able to bring this technology to travel photography.
4K3D is the highest possible quality that photography can be presented on large format commercial electronic displays and projectors in 3D in 2017. This website is dedicated to users of 4K3D display technology and virtual reality displays.
4K means about 4000 (at least 3840) pixels horizontal resolution (and 2160 pixels vertical resolution). 3D stands for three-dimensional that exactly means stereoscopic, separate pictures with slightly different horizontal viewing angle (parallax) like seen with two eyes. Stereoscopic photography is not a new discipline but more than a hundred years old. However, never before there was the technology for such a superb presentation of the results to so many viewers. 4K3D is the cinema standard of today where blockbusters are shown in theaters using high definition projectors and 3D glasses.
3D photographic results also can be shown without any crosstalk on a virtual reality display like Oculus Rift VR or Samsungīs Gear VR using the Note 4 or Galaxy S6 smartphone. An up to 360° panorama view in 3D can be achieved using those displays and software-composed panorama photography.
For my stereo photography I use a self assembled dual-DSLR rig to shoot for the leading edge UHD/4K 3D-TV displays and projectors as well as virtual reality display technology.
4K3D TV displays and projectors have been available for a few years now. 3D-bluray content can be shown on a passive 4K display in Full-HD 3D (1080p), which means very good quality for 3D without flickering because of using polarizing filters in the 3D glasses. But besides video, 4K3D displays now lead to a new era to present and view 3D-photography in ultrahigh definition !
I assembled the Nikon "DD300" dual-DSLR 4K3D-stereo camera in October 2013. It is shutter-synchronized down to 1/8000 sec., above shown with Nikkor 18-105 mm zoom lenses. However, most of the time I prefer the 18-55 mm zoom lenses for weight and size reasons but also shot using 80-300mm tele zoom lenses. I prefer the .mpo 3D-format that can be read by 4K3D-TV (via USB 3840x2160px per eye on active 3D systems) and bluray recorder. Thus, I consider this "DD300" a very elegant digital 3D-SLR camera providing professional features. The DX format sensor allows more compact zoom lenses and more depth of field, an essential feature for 3D photography. The assembly is a slightly hyperstereo design and I like the impressive 3D results. So I donīt think it is worth to fix the Nikons on a z-rig to get the lenses closer together since usability really gets worse. Because I shoot for virtual reality display, screen and projection I nearly exclusively use landscape format. Original format is 3:2 as in published photography, which is the more usable format for virtual reality. For 4K3D displays I crop to 16:9 format, since the D300 provides 4288x2848 pixels and a 4K image is 3840x2160 pixels.
What about active or passive 3D ? Both systems have advantages and disadvantages. Active displays lack brightness and show more crosstalk artifacts. There are no active 3D-TVs on the market anymore. Passive displays reduce resolution to 3840 x 1080px per eye when switched to 3D mode. This is not noticeable from normal viewing distance (>2m for a 65 inch screen) that should anyway be kept to obtain a good 3D effect. The advantage is less crosstalk and flicker-free bright picture. If you are interested in 3D-TV get an (OLED) Cinema 3D display as long as it is available. Sadly, LG stops production in 2017 !
HOW TO VIEW MY PHOTOS IN 3D e.g. on YouTube or phereo.com/romanklein :
- ON 3D-TV OR 3D-PROJECTOR ( best quality )
Open my video slideshows on YouTube in 4K3D on a 4K/UHD smart 3D-TV or a "non smart" 3D-TV switched to AppleTV or Google-Chromecast using the YouTube-App, or a PC using the YouTube website in full screen mode, then set 3D on your TV to side-by-side or top-bottom regarding to the video format and use 3D-glasses provided by TV manufacturer. Usually there is a 3D button on the remote control or a MENU button opening a 3D menu. On Samsung TV you may need the blutooth smart-remote to access the 3D menu. YouTube is supporting 4K3D-2160p content that uses every pixel of passive 3D displays. Therefore I prefer TOP-BOTTOM 3D format which is better for passive 3D systems and no disadvantage for active 3D systems.
- ON THE PC
You may switch your PC via HDMI to a HD- or UHD 3D-TV. On YouTube you must use fullscreen mode for my 3D videos specified for 3D-TV and then switch the TV to side-by-side 3D format or top-bottom-3D format (optimized for passive 3D systems like LG-cinema3D), respectively and use 3D-glasses provided by TV manufacturer.
An easy and comfortable way to view my images in full colour 3D is also to use the NVidia 3D Vision system (e.g. the NVidia 3D Vision 2 Kit for PC with GeForce graphic card and a 3D capable PC-monitor).
You may also switch your online computer to any 3D-TV or 3D projector via HDMI cable choosing "3D-TV output" on the phereo website.Here is how to do it with a PC and a 3D-TV with a HD panel (1920x1080 px):
You need a PC with internet access, Adobe flash software and HDMI connection to use the 3D-TV as monitor. Choose resolution for the graphic card 1920x1080 pixels. Go to www.phereo.com/romanklein. Choose one of the 14 albums that you want to be displayed in 3D. Click on the first photo of this album. At the upper right corner you can choose between "3D TV", Oculus Rift" or "Fullscreen". On the lower left corner you can choose between "3D Vision" (only if you use a NVidia 3D computer), "Interlaced" that is suitable only for passive 3D displays, e.g. LG Electronics, "Anaglyph" for red-blue filter 3D glasses (rather inconvenient), "Parallel" for parallel view technique that must be learned, "Wiggle" for animated left and right picture (pseudo-3D), and "2D(Left)" just for normal 2D display. On the right you see "Swap" button, that changes left and right image: so "Parallel" changes to "Crossed" for crossview technique that must be learned and 2D(Left) changes to 2D(Right) now showing the right image of the stereopair. Choose "3D TV". You will now see left and right image of the stereopair side by side. If the browser does not switch to full screen mode automatically choose "Fullscreen" or use "F11" key on your keyboard! Now you will have to tell your TV that it is receiving a 3D signal input, so use the TV remote control and press the "3D button" or use the menu for 3D switch (Usually you will get a menu to choose the side by side format that must be applied). Use your 3D glasses that came with your TV (can be shutter type (Samsung, Sony, Panasonic) or polarizing filter glasses (LG cinema 3D, some Sony TV). You should see the image in 3D now. If there are troubles with left and right orientation, press "x" on keyboard to swap left-right ! To switch to the next image, click with mouse to the image once (loading image may need a few seconds). To finish, switch first your TV to 2D mode with remote control and then end the 3D-TV mode on computer by pressing "ESC" key on keyboard.
On passive displays you also can choose "Interlaced" mode INSTEAD of "3D-TV" mode, BUT I observed relatively strong ghosting image artifacts and the need of swapping left and right (press "x" on keyboard when you are in full screen mode) can be high, depending of resolution of image uploaded. Therefore I strongly recommend the side by side 3D-TV display mode for this purpose (i.e. 960x885px/eye on active 3D, 960x540px/exe on passive 3D).
If you have a Smart-TV with internet connection, the internal webbrowser may eventually not work for the purpose of 3D viewing. Please use the YouTube App if you want to view videos from my 3D channel.
- ON SMARTPHONE WITH VIRTUAL REALITY EQUIPMENT
On a smartphone with a 5 - 6 inch display load YouTube-App and use Google Cardboard / Daydream or free viewing parallel technique for side-by-side full width 3D. I recommend a smartphone with at least a HD display (1920x1080 px). You may also use YouTube on Samsung Gear VR or technology from any other company. Be aware that you cannot get a superb picture quality from any smartphone and VR-headset (you will always see pixelation) compared to a 4K/ UHD-3D-TV!
- WITH OCULUS RIFT
If you own an Oculus Rift VR you can choose that display mode on the phereo website (when using Firefox- or Chrome browser).
- WITH OLD FASHIONED AND TECHNICALLY OUTDATED CHEAP RED-CYAN 3D GLASSES
Anaglyph format for red-cyan 3D glasses provides 3D for everyone. However, it is not really comfortable to view and colours are reduced.
Image sample shot on Kangaroo Island, South Australia, in red cyan anaglyph technique. Use red-cyan glasses to view in 3D.
- WITHOUT ANY OF THE ABOVE
If you donīt have a 3D-TV or 3D-PC or VR equipment there are several options to see a 3D image the way itīs meant to be seen. The first two methods (parallel - and crossview) you will have to learn, but there is no guarantee that it will work. Search the web for tutoriaIs. It is possible to learn it within a few minutes. If you donīt succeed, get a mirror stereoscope that is usable for both formats. A modern mirror stereoscope (e.g. Pocket 3Dvu from berezin.com or similar from dx.com) for less than $30 can give you a fair (but only small format) 3D-viewing experience.
Example 1: parallel view - Keep side-by-side photo very close to your eyes, fully relax your eyes and move slowly backwards so that both pictures can be focussed and merge to one 3D impression. It is the same technique as used for the magic eyes books of the 90īs. Important note: Keep images on screen smaller than 7 x 5 cm ! (can be done best on a tablet, will be impossible on a larger monitor at close distance !)
Example 2: Alice, the tired kangaroo from Alice Springs in crossview technique.
Available formats of my photography on phereo: nVidia 3D vision, interlaced, anaglyph (red-cyan glasses), parallel side-by-side, crossed side-by-side, wiggle mode, 2D mode, 3D-TV (compressed side-by-side), Oculus Rift format for virtual reality display.
The stereo-photobooks AUSTRALIA 3D can be found on my blurb.com site.
See 4K3D videos on YouTube for 4K/ultraHD 3D-TV in native 2160p.
You can find side-by-side and top-bottom 4K uploads for 3D TV as well as Google Cardboard / Daydream format in HD for VR on YouTube !
4K streaming needs 16 Mbps internet speed or more, otherwise you will get HD resolution or lower.
