After using a small el-cheapo changing bag and finding out the hard way that infrared light thinks that the bag is transparent, I am looking for an alternative. I often use 35mm Efke IR film, and though I like the results of this film a lot I dislike that is has a serious light piping problem because the base is a sort of polyester-something, it needs to be loaded in very, very subdued ligh. Quite often, when travelling by bike, I find that the weather is perfect for infrared photography but that means there is no dark place to go and no space for a ready-to-go changing tent.
So, travelling by bike means, I am looking for a small, lightweight changing bag or tent that I can setup quickly. I would prefer a tent, in fact, but they are big. How much time does it take to setup a Photoflex or Harrison tent?
