Wedding photography is the photography of activities relating to weddings. It encompasses photographs of the couple before marriage (for announcements, portrait displays, or thank you cards) as well as coverage of the wedding and reception (sometimes referred to as the wedding breakfast in India).
A candid photograph is a photograph captured without creating a posed appearance. The candid nature of a photograph is unrelated to the subject's knowledge about or consent to the fact that photographs are being taken, and unrelated to the subject's permission for further usage and distribution.
Evoking emotion simply means that your photos say something. They may speak about something funny, moving, sad, or thoughtful. They might capture a mood, or put your viewer in a state of contemplation. Photos that evoke emotion simply portray a feeling.
