Dear Emily,
I have visited your website, and I see that a large part of it is dedicated to the three dimensional virtual tours for viewing on VR Gear devices. I know some of the advantages of the system you are using, and that is why I am pleased to inform you that traditional photography can already achieve these results, to which we can add HDR capture, RAW capture, and 27K resolutions.
I know this is not what you’re asking for, but I think it’s interesting for you. Sincerely, Javier. https://vr3d360.org/
