I am Dennis from Bulgaria and I am the creator of one of the few bulgarian 360 websites. I am filming with a 360fly 4k camera and I mostly edit my videos with Adobe Premiere. About the website that I mentioned - it`s new and I am uploading new video content every monday. If somebody is interested in Bulgaria and wants to see different interesting places in my country, this is the website: http://360videos.bg/
You can also subscribe for my youtube channel: https://www.youtube.com/channel/UCuhJB74g7FSTD59-q-Fz8Wg
Or like my page on facebook: https://www.facebook.com/360videos.bg
I would be happy to share my experience if somebody needs help. Cheers!
