End of the beforegoing.
Apart from being ... well ... large-sized, Jeff Wall's photographs - are interesting.
Let's take for example
On first sight it looks easily done, like a snapshot, but ...
What I like about Jeff Wall: He does not wish to transport a mission, he does not even intend to tell a story (at least he says so); he leaves all to the viewer / contemplator.
It is as if a reader writes the story, each reader his own.
Huh, however: two or more years preparation for one photograph - that's a bit ...
... but who am I to complete my thought(s)?
Am I not a bit ..., myself?
Aren't we all?
Or, at least, most of us?
What do you think?
* With pleasure I do once again commend to read A Doubtful Egg's post about Them Bleedin' Artists ...
Take your time, contemplate, reflect and ... leave him your opinion.
** There is quite a lot to discover in Tate's Gallery and Moma.
