The photographer could go the extra mile for the client by researching how the ceremony goes, or get briefed by you or a member of the family. On the other hand, it would be more convenient to hire a veteran who handles Asian wedding photography in London, like someone from Pixcellence Photography. Such services will be well-versed in covering Asian weddings.
One less worry
With the multitude of things on your mind, the last thing you need to worry about is directing the photographer throughout the ceremony, and worry if his timing was right. This is the day you and your spouse mark the beginning of your journey in life together as one, and it deserves to live on in your photographs as well as your memories.
