The panorama head should be FIXED on a tripod, TO ensure the nodal point of the lens FALLS RIGHT on the rotation axis when the camera turns around. Without the panorama head, the PICTURES taken SIMPLY WITH A digital camera and fish-eye lens will migrate (DEVIATE?).
看你还是有一定基础的,就不费事指出怎么修改的了,自己看后整理好了.术语自己查对无误吧,最后一个词严重怀疑,但不知道你说的具体是从哪里偏移,所以我的建议词也不一定对,一般来说要加上from .才完整.
