What are some of the different genres of photography?

Description from Wikipedia wikipedia link

Fine art photography is photography created in accordance with the vision of the artist as photographer. Fine art photography stands in contrast to representational photography, such as photojournalism, which provides a documentary visual account of specific subjects and events, literally re-presenting objective reality rather than the subjective intent of the photographer; and commercial photography, the primary focus of which is to advertise products or services.

I would say that I cover all these genres in my photography pursuits. I love to capture the photojournalism aspects at events, capturing a story throughout the numerous captures. Hopefully leaving a viewer the ability to picture the event as a near full entity as possible. The commercial side is important as it is needed to present a capture to the viewer that represents a true state, not something graphically altered to enhance the result and therefore misinform. For fine art, this is when I can use my interpretation of what I saw before pressing the shutter and what the camera was able to capture and enhance aspects to lead a viewer into the scene, creating the journey or meaning I wanted to portray. 

Photography to me are all these and the resulting genre is realised with the end result and objective in mind.
