TS> <http://www.pauck.de/marco/photo/infrared/comparison_of_films/comparison_of_films.html>> Tim, thanks! That's exactly what I have been looking for. Now, anybody would know the spectral transmission of my IR filter ;-) ? It's the East Germany's Panchromar brand (btw quite good with regards to glass quality and grinding q.), labelled IR ROT, FILTER B. I can see tru it, but only very very faintly and only the bright light sources like bulb, white clouds, etc. The brochure that came with it is generic and not much help :( IT lists two IR filters (one "durchlässig, rotdunkel, dämpft Violett und Blau bis zur vollstandigen Schwarzung", the other "infraschwarz", "schwarz", "ins extrem gesteigerte wirkung gegenüber dem infrarotfilter"). From my remembering of Deutsch, I would have the first one, possibly. but what the cutoff is, I dunno. I wanted to use it with the SFX film.
