If you want to learn new techniques for Adobe Premiere, Photoshop, or other Adobe products, you can register for Adobe MAX 2021, which will be held October 26 to 28. There is a section for AR, but I haven’t found any sessions directly related to VR or 360 yet. Nonetheless, some techniques for editing photos and videos may be usable for 360 photos and videos.
Adobe MAX is an annual conference for Adobe. In previous years, admission to Adobe MAX usually cost over a thousand dollars, such as the one shown below for 2019. With the pandemic, the conference became virtual and free in 2020 and they’re continuing that in 2021. Hopefully, even future conferences will be free.
