I met Xiang Ni when I was the photographer for her best friend's wedding. Xiang Ni contacted me not long after the wedding and everything else was history.
It's easy when you are working with couples that get to see how you work 'on the field' to eventually seeing the final set of images. So they appreciate why the photographer gives a certain set of direction during the shoot to get the final image he has in mind. Sometimes photography makes people uneasy if you are camera shy, and when you want to look good on your most important day but not knowing if you are doing the right thing!
Im quite sure this couple knows exactly what they are doing :)
