Solargraphs in this month's New Scientist

[Christopher Walrath]

I had forgotten about Justin's website. I visited it about a year ago. He has done some work for the magazine. Very inventive photographer.

With the winter solstice approaching I'm going to have a go at these. The only question I have (at the moment) is whether or not any sort of ND filtering is required or does one just use a 'standard' beer can pinhole camera or such like ? I know photographic paper is slow but 6 months of 12 hours average exposure per day seems a bit much even at f/200.
Any and all advice gladly recieved.

I did read that, but it just seemed too simple. Maybe I'm just too cynical
Oh well, I'll just have to wait 6 months and see what happens. Now, what to do with that beer I need to empty from those cans...
