4x5 Velvia is a very popular film as everyone knows. I would like all input from users as to the reciprocity times they found in practical field shooting at ver y slow speeds. Also any usefull info on the exposure limits(sunny day) shooting vs overcast day. Nightime shooting also. Any metering hints for using a hand h eld spot meter (fast) to come up with on the nose exposures in any lighting sit uation. I would like to hear from those who have been there and done that. No s peculations please. Contact: talltandj@aol.com Tom
