"I've seen that before..."

If you've been involved in wedding photography for quite a while and spends some time surfing the web looking at other photographer's work I bet you will start to notice that many shots are being repeated again, again and again by many photography across the globe. "Now where I've seen that ring shot before? or that window shot or that bouquet closeup, even that outdoor shoots". Is there a creativity crisis among us wedding photographer? Or is it a norm for certain 'moments' to recur and repeat itself over and over again?
Come to think of it, creativity or the lack of it may not be the only factor for this Deja Vu effect. Weddings are a cultural as well as a spiritual event with a central focal theme which is the solemnization of love of two individuals and its no surprise that this common theme resonates all across cultures and religions. To an observer lest he is a photographer or not this central theme surfaces into recognizable scenes worthy of immortality. What this have to do with photography?
All throughout the history of photography many themes tend to recur again and again and this have nothing to do with plagiarism. Some of these photographers never even seen the work of another yet their works seems to be thematically similar. In his book 'The Ongoing Moment' Geoff Dyer systematically analyzed these recurring themes throughout the history of photography. Even those iconic images by masters tend to have a repeated theme.
Does this mean that wedding photographers should not be looking hard for this elusive moments as they were not that elusive after all? Of course not, as these moments may only reveal its beauty to an observant and experienced eyes ant it is through our eyes, the wedding photographers that this central theme of love is recognized and captured. Maybe this is the real reason so If you saw that photo somewhere before it was not lazily copied but rather mysteriously resurfaced from a endless pool of moments.
