It depends on the subject you are shooting. If it is nature, low sky
light, I have had the best results with Velvia, which has the least
color shift and reciprocity failure with long exposures. Here is a
table for the "approximate" reciprocity correction needed for long
exposure times from John Shaw's book *Landscape Photography*, p83.
Film 1sec 4sec 8sec 16sec 1min
-------------------------------------------------------
Kodachrome 25 +0.5 +1.0 +1.5 +2.0 +3.5
Kodachrome 64 +1.0 +1.5 +2.0 +2.5 +3.66
Fuji Velvia -0- -0- +0.5 +0.66 +1.33
Fjuichrome 100 -0- -0- +0.3 +0.66 +2.66
He uses Velvia for long exposure and no color correction. Interesting
in that Kodak does not recommend using Kodachrome 25, 64, 200 or
Ektachrome 100x for exposures 10 seconds or greater. Fuji does not
recommend their film for exposures at 1min.
