Hello! I wonder if anyone can help? I'm going to Paris tomorrow for the day and I have a roll of Kodak HIE infrared film which I've never used before. Depending on the weather I might use this film with a B+W 091 dark red filter that I have. It will be for outdoor shots. Does anyone know which film speed I should set the camera to? The film packaging only mentions Kodak Wratten filters and I'm not sure which one would compare to the B+W?
