In VR porn, 180° and 360° refer to the camera's horizontal field of capture — and the difference matters more than it might seem. A 180° scene distributes all its pixel budget across the front hemisphere, delivering sharper detail on the performers; this is why nearly every premium studio shoots 180° today. A 360° scene covers the full sphere, so resolution is spread thinner and the back half of the frame is typically empty or shows a minimal set. The main reason to prefer 180° is image quality; 360° is mostly a legacy format still found in older catalog titles and some exhibitionist voyeur shoots.
