[alt-photo] Re: Ultra Long Exposure Reciprocity Failure?

[Loris Medici]

Francesco, I'm big fan of Michael Wesely's work, especially the
Potsdamer Platz series!

Anyway, I dont think those are ultra long exposures, I think they're
time lapse recodings...

I use the simple formula T^1.48 for my pinhole exposures on Ilford
film, works great! (Found that from APUG...)

Regards,
Loris.
