well... in my humble opinion is that street photography would be define simply by being able to to document a part of a city/life/street and it would prompt thoughts, ideas or even feelings.
what gold fries shown wasn't common and yes i would say its considered a street photography shot as it includes him taking a journey through the town/village or city and capturing something in angle that prompt a thought to him in which we don't understand.
like i've previously mentioned, photography is an art. photographers are artist. we paint with our camera and view life through the viewfinder just like how artist paint with brush and view life through their own eyes in their own perspective. generally, an artist would have a specific theme or title or a phrase/word to accompany an art they have done as to give the viewer an hint on the direction of his perspective.
how each and everyone of us view an image is different, some may be same as we're influenced the same way but even if we maybe thought the same we would still have a different output. most of us went through the malaysia's public education syllabus, taught by teachers but we each went through it differently and we get to feel the same thing differently.
as referral to the color image of a lonely guy in the backalley with wonderful colors in it... i think it brings a thought to my mind, how a person can look so sorrow and how a BACK alley can look so colorful when most of us would perceive back alley to be dark, dirty, black, and filthy?
how we include a living object in a shot to portray a story is something each of us view differently, how one shot of totally nothing could mean something?
