I have used a lot of Rollei Superpan 200 film for IR effects and like what I'm getting. It has extended red sensitivity to 750nm and works well with an R72 filter.
I understand Rollei's Retro 80S film also has extended red sensitivity to 750nm but I have not used it yet. Has anyone got experience of using both films and how they compare? I'll try it soon but I'm just curious to hear from other users.
