I read an article in 2009 written by a British photographer whose name I do not recall in which he said the following.
Photographers do something really special. They capture special moments in time probably never to happen again and preserve these special memories for the owners to view at any time they choose which help bring them back to visualize that very special memory. Will people continue to want this service I think so
Do people want help in capturing those special memories in life? Absolutely will they always do so? I think so, so never underestimate the importance of the job you do. As far as I am concerned helping to preserve people's memories of events that will probably never be repeated is a very special and important job so I urge you to portray this in everything you do.
I trust you will enjoy the moments in time I captured.
