請教各師兄拍攝合照相時2人以上"分開站企"應可用多少光圈才會看得面孔清楚? 因本人多次影合照相時都發現會有一些人出現矇既情況 ! (鏡頭 Nikon f2.8-4 24-85mm) , 是不是一定要收細好多光圈才會清楚的 ?

Yes, "收細好多光圈才會清楚".

You should have enough "depth of field", which is necessary to cover those guys faces at least!

Other than aperture, the focal lenght is closely related to the DOF too!
The shorter focal lenght you use (e.g. 24mm), the deeper DOF you may result. Long focal length & large aperture are not familiar for group photos in most of the case.
