Cambridge and Pakenham Mills with R72 Filter

I experimented with using an R72 (dense red filter) with my Fuji to give a pseudo infrared image while in Paris (http://pin-sharp.blogspot.co.uk/2014/12/trees-and-shadows-from-paris.html). I have recently been trying a few further shots first in Cambridge and then at Pakenham Wind and Water Mills on the way back from the EAF Exhibition at Wingfield. I have not yet found how to do any type of satisfactory colour conversion but do like the contrasty monochromes from the files.
