Having looked through the 3 weblinks given, I personally am very attracted to "Street" and "Spot News" photography. These two genres of photography poses a very big challenge to the photographer as the subjects/actions are ever changing and a second late, one would have missed the most magnificant photo momement. Having a sharp eye and of course quick response plays a large part in capturing these moments. Apart from these aspects, most of the time, as such photo moments are rather impromptu and can even catch the photographer by surprise, the outcome of the photos can capture and convey the most natural, real and "raw" message.
To end off this post, I will share with you guys a amateaur "Street" photography i attempted when I was at Taipei a few months back.
This photo was shot at a underpass in Tai Zhong. Personally I felt it wasn't a very well composed photo and it lacks a "story-telling" factor in it.
