Just read this in a Macau photo forum. I found the following "formula" a very accurate description.
好相片的元素精彩照片=（光圈+快門+感光度）+（焦距+構圖）=（曝光正確）+（精彩構圖）
A good photo = (Aperture + Shutter Speed + ISO) + (Focal Length + Good Framing) = Correct Exposure + Good Composition
In a studio photography like this set, the more technical exposure elements are under control. But getting good framing needs lots of imagination and pre-planning. What we did this time was just walk in and shot whatever was shown to us. It get boring after 10 or 20 min.
Comparing to studio photo, event photos like sports or
dance competitions offer lots of good framing opportunity because of the constant changing motion and genuine postures. But getting the right technical elements together is much tougher. Either the lights are not right, or shutter too slow.
