Originally posted by asahijock Can you remember the ISO you used? I have a P645N so a film user. The top ISO in colour is quite limited compared to a digital 645 hence my worry that your ISO might well be higher than I can achieve with film, using even a 1.4 let alone a 2x.

The exif indicated it was shot at 800 ISO. So Kodak Portra 800 would be your best bet with color, and I'd probably go with Ilford XP2+ at EI 1600 with monochrome.
IMO the first three shots with the single TC looks acceptable, but the double stacked TCs looks flat; loss of contrast and color.
