The spec sheet for Velvia says reciprocity problems begin at 4 seconds, and at 16 seconds recommends +2/3 stop and a 10M filter. (As I recall.)
But I don't really know what that really means. Do I simply expose it for an extra 10 seconds to accomplish the +2/3 stop?
Next, if I get a color shift that can be corrected with a 10M filter, can that be corrected identically in photoshop? Or is there loss on the film from the color shift that can't be fixed digitally?
Thanks in advance.
