Hello, Im a little confused regarding Stereo Panoramas or 3d Stereo Panoramas. My current setup is a 6d / 8mm and a NN R1. In order to create Stereo panos, I need 2 cameras? Or do you call a Stereo Panorama when its process/coded to view it in VR?

it is sort of like audio, recording (shooting) and playback (viewing) are separate things, you can record a single track in mono and playback in 2 channels, but it is not the same thing as proper stereo audio recording and having proper stereo playback
so if you shoot one pano and display in a VR viewer, this is a sort of “false stereo” double monaural playback, shooting 2 proper stereographic panos and VR viewer would be “true stereo” playback

Thank you Sam for your reply. I had that question because I saw this sample from Krpano, when you see the menu there are 3 options, 1 one them are called STEREOSCOPIC 3D PANOS and NORMAL 2D PANOS.
So Stereoscopic and Stereographic is the same? and they only apply for VR? When viewing a panorama on a regular monitor, is there a much different quality from shooting with 2 camera setup than 1 camera?
Sorry for asking this questions, but im very confused.

dont worry about this being confusing, it is ;)
stereoscopic and stereographic are totally different things, stereoscopic refers to “3D” stereo vision, stereographic refers to a flat image projection like a little planet
if you look at the STEREOSCOPIC 3D PANOS in VR mode on desktop, you will notice that the 2 side by side panos are slightly different, foreground objects will shift slightly vs background in left vs right pano, if you look at the NORMAL 2D PANOS you will notice they do not display this shift as they are not “true” stereo, and there is no quality difference or other real advantage for “3D” stereo panoramas on a desktop monitor unless you wear theater style 3D glasses to view it
if you look at these panos on a proper VR headset, you should get a more convincing “3D” experience from the true stereoscopic “3D” panos vs the normal “2D” panos, but also see this link to jürgen schrader‘s pano for a good example of successful 3D stereo shooting and stitching
as a bit of parallax (which is normally undesirable for shooting panos) is required to make this work, how much of a difference this actually makes in a VR viewer at the end depends on the location and final quality of stitching, if everything is far enough away and no foreground/background parallax shift like a mountainscape etc, you will probably not see any difference in “2D” vs “3D”, and the required parallax inherently makes good stitching difficult if you do have the nearby objects to pull this off, so making it work convincingly is a careful balancing act in the end

Hi Sam, sorry for my reply but thank you for the explanation.
I have a Vive, I will check the link and see how it looks. Now, im afraid to watch it and if its looks really good I will start obsessing over Stereo Panoramas and spend time on learning and getting the gear while currently im trying to improve my regular 360 panoramas (shot and post) and did I mention also 360 video ? …when will it stop?November 26, 2016 at 4:57 am #11299
yes, improving basic photography technique is more important than jumping on every new technology that come along ;)
there is also PHOTOGRAMMETRIC 3D where multiple panoramas are used to generate a true 3D model, which allows moving around in a true 3D dynamic environment like a video game vs the static environment of stereoscopic where one can only turn your head in a fixed position in space
have fun ;)
