The Helsinki Bus Station Theory: Finding Your Own Vision in Photography (2006)

For me the advice boils down to: don't worry if your plays mention dogs or include cousins just 'cause a famous author's plays do too. Which is true advice, just not that useful in bringing into the Valhalla of real art.
My advice would be: Do offend your peers and court their contempt. Almost no-one else will do this, so you can hardly help creating work that's original and which might survive with its reputation intact, which happens rarely with art.
I googled it, and all I see is a very ordinary, modern, un-beautiful bus station, like the ones you find all over Europe, so I'm having trouble understanding why it's a "cool backdrop" or "famous" (other than the author using it as a convenient metaphor).
So Helsinki is an example, maybe not unique, of a bus station where it takes some time for (at least some of) the different numbered buses to diverge from a single route ("career trajectory").
To me the article said the bus station is famous first for his students because he talks about it in his lessons. Here in Helsinki we like to think that the railway station has some merit on international scale, bus station by itself doesn't rate that much (and those are disappearing underground anyway).
From artistic point of view (I only shoot with phone camera)... It's a bus station servicing east and north eastern lines. It gets travelers from airport train in addition of near and far going trains. Also, underneath is metro station, other side of the railway station is another bus station for north to westward lines (additional western lines are close by though that one is underground).
So, lot's of different people going through which affords various views against backdrops of various (to me spectacular) specimens of Jugend architecture through (particularly nasty example of) concrete brutalism (which writer neglects to mention for some reason..).
