Just because you weren't paid doesn't mean that what you did isn't photojournalism. The point of the pictures was to show, from your point of view, what was happening. That's photojournalism. Whether or not it was "newsworthy" would depend on whether or not a news organization wanted the pictures. And if you're with friends and family and you shoot pictures to show you were there, those are what I call tourist pictures.
It doesn't matter. What you're missing is a background in the history of photography. People get hung up on verbal definitions, but you can't define some things with words. To understand what street photography is you have to study the works of the people who defined it with their pictures. I'm not going to give a list of those people here. There are lists all over this segment of LuLa.
