[pinhole-discussion] very long exposure

[Hugues Mertens]

Hi,

I have the project to expose a color negative during one year with a 
pinhole camera...
The picture should represent the trajectory of the sun from winter to 
summer solstice and inversely and, I hope, a weird representation of 
the landscape.
I'm thinking of using a ND 120 filter (-20 stops) to achieve that.
Does anyone has already experiment that kind of exposure with another 
solution ?
