Ethics.

"Moral principles that govern a person’s behaviour or the conducting of an activity."

Something that plays a large role when it comes to professional photography is ethics. It's quite clear that no two Photographers have exactly the same views on ethics and it's not something that's widely agreed upon. Take one of my previous blogs for example. Bruce Gilden claims to have no morals when he's taking pictures. He see's that he has the right to do it, so does.

My previous blog about Bruce Gilden:

Many other people would see this as invading peoples personal space and borderline harassment.

As of the 15 March 2014 in Hungary, It's now illegal to take street photographs with out prior consent from the people in the images.
