"能不能拍出一个效果: 小姑娘的眼角膜表面变成一个光亮的镜子,清楚地显现眼前的人像? 器材上有什么要求?"

Sorry to take so long time to get back to you, very busy day today.

I have not tried but what you say is possible. A) for the best result, you have to use Macro shots (some small digital camera will do). 2) get some light on the people you what it to be in the eye rather than the eye you want to shot. 3) choose a good angle and try it out.
