It's important for a photographer to have a sense of humour I think. It helps us cope with the unexpected and to laugh about it later. Eventually! It's also a vital tool for getting on with clients and helping to create a rapport which is vital for great natural looking photography. A sense of humour can help them relax, make them smile at the right moment, or laugh if your jokes really are that good, (or bad!). It's part of the skills mix that photographers need, especially if they work with people.
It's also important that clients get a sense of who a photographer is as a person and not just the standard of their work. I have many friends who have been disappointed with their choice of wedding photographer because they felt they were intrusive on the day. One friend remarked that their photographer didn't smile once and that they didn't feel relaxed at all. You can tell from their photos too. They look tense. A couple booking their wedding photographer will want someone with them on their day who they can relate to. They are entrusting a virtual stranger to capture their memories. A little humour goes a long way to helping make sure that these are happy ones. There are limits though, no-one wants a comedy act behind the camera (well most, someone might!) so leave the Fez at home!
Anyway, Happy Easter. I thought the little animated video was apt for this weekend. I'm a big fan of Simon's Cat, being a cat owner myself and a little sense of humour helps there sometimes too! Hope you have a lovely Easter.
