Housing what was once the largest telescope in the world, this observatory sits on the hill behind where I live. This tree has long been my favourite in the area, and I waited a long time for a windy but clear spring day to get this shot of the tree and the observatory on IR film.
Thanks Kevin. Superpan is a Rollei film. I used to use Rollei IR exclusively; lately I prefer superpan for medium format and efke IR for larger formats. I rate it at 200, give a ~10 stop filter factor with a #87 or ~3 stops with deep red, and dev for 10 mins in wd2d+.
Thanks! Wolfeye, it definitely is IR film, I would compare it to efke 820. Note that the filter I was using with the superpan was quite deep, well beyond the 72 filter that many folks use. Anyway, with a red filter you can get strong tones too, see here.
