Velvia pulls poorly. Flashing will muddy the shadows. If you use neutral grads they it will probably look just as
corny and phony as when Galen did it, but whatever. I'd carry more than one film so you can match the lighting
of the specific scene. If I had to use it in bright sunlight (and have), you often just have to let the shadows go
black and compose accordingly. Generally a lesser evil than blocking up the highlights. I prefer Velvia in diffuse
lighting where its higher contrast and saturation is warranted. Can't imagine using it without a spotmeter, however.
