How to make such a 720-degree panorama? More specifically, how to shoot the required material?

SLR camera, tripod, tripod, fisheye lens. For example, Canon 5D2 is equipped with 8- 15 pan/tilt, and it takes 6 shots in a circle, so there is no need to fill the sky. Post-splicing pictures with PTgui. It can be spliced into a panoramic view above you, which can be supplemented by PS or directly in PTgui. Hope to adopt! ! !
