Does anyone have any experience with this? The base exposure should be in the range of 2-20 seconds with my 5x7 f/270 pinhole camera. Kodak Publication E-4040 doesn't give much to go on. Are there any other 5x7 color films, chrome or neg, that have better reciprocity characteristics? I'll start out with Portra since I've got some in the freezer.

I should have searched the archives first the info is there. Sorry for the waste of bandwidth.
