An open letter to YOU, inconsiderate photographer,
I understand that you have a camera and want to get original, in your face, action shots. I, too, like to do that sort of thing. I understand that you want to immediatly see that cool picture that you just took. I understand that some people want their photo taken as they are running. I understand that at the back of the marathon people are running slower.
What I don't understand is why you think you have the right to go into the middle of the street and literally step directly in front of people and fire off your shot, continue to stand in front of them and the people they are running with, then look at the picture you just took, and forget that there is a race running around you.
These people are running 26.2 miles. Have you ever done that? Have you ever had a pace or rhythm going that you didn't want to stop? Have you ever had someone step in front of you to take your picture?
There are barricades on the street for people like you. Stay out of the race, stay out of peoples' faces, be considerate of other people, take creative portraits in another way, learn technique.
You are a rude photographer. I was ashamed for everyone who has ever held a camera today.
Look below to see more examples of your rudeness.
