Saturdays Online: How Long is Too Long?

As I prepare to set out more Solargrams for the Summer/Fall,

I am pondering this question:  How Long an Exposure is Too Long?  How about a 1000 year exposure?  The question is who will be around that cares or even remembers?  Although, placing it on a University Campus does improve the chances of survival.

But this is not the artists first longterm work, as Mr Keats continues his habit of long exposures with an earlier (and still ongoing) project in Berlin.  Read more about 100 Cameras for 100 Years.
