Using humor is a great way to draw attention to your photography.
Doing so relaxes tension. It allows us to take ourselves less seriously and keep us amused and entertained.
Humor can't be forced. It is a gift from the universe that lands in our lap when we are lucky. But like everything else it happens more often when we recognize it and focus on it.
One very important thing to remember is that something is only funny if everybody in the room agrees that it is.
Whatever is viewed as disrespectful leaves an unpleasant, sour taste in the mouth.
