Reciprocity information of Fuji films is easily available in nice tabluar form. I am having a devlis own job of finding the same for current Kodak films (E100G / Portra / Ektar 100) all of which seem to assume that exposures of longer than 10sec arent required....

Anyone have summary tables or know how to create them ?

Thanks

Its not one of your listed films, but there is data given for E100VS in Jack Dykinga's book. I can't remember exactly but I think it simply said that above about 8 seconds you just need to add 1/3rd of a stop, so not a great deal. I have no idea if E100G has similar performance.
