Without a fish-eye lens, you can’t get AN ideal panorama picture, especially (删掉,) when we want to take pictures of a FULL (删掉n entire) spherical scene with A PERSON IN FOCUS/IN THE CENTER（删掉a center of a person）. THE Fish-eye lens can capture images FROM A (删掉with) 180-degree PERSPECTIVE (删掉viewing angle) both horizontally and vertically, so (删掉that）WITH IT/BY USING IT we ONLY (删掉just）need to take two pictures of the scene to make a panorama photo.

大写的是新加的，括号里是要删掉的，还有个别标点改动就不标出了，自己看吧。改后句子语法肯定没问题，但专有名词如鱼眼镜头什么的就靠你自己去核对了。追问改后
Without a fish-eye lens, we can not get an ideal panorama picture, especially（一定要删掉？） when we want to take pictures of a full spherical scene with a person in the center. The fish-eye lens can capture images from a 180 degree perspective both horizontally and vertically. Therefore, with a fish-eye lens, we only need to take two pictures of the scene to make a panorama photo.追答说要删掉的是那个逗号，没有必要反而把句子搞断了。后面180和degree之间要加-,否则是180 degrees才对。其他的都对了。

with a center of a person 我觉得换成with a center of the person 要更好一点追问可这人不是特指啊。。。
