Hi all, I'm planning to take some nighttime people shots after having bought some Fuji 800 and 1600-speed films, and am planning to use fill-in flash after receiving some helpful advice on the subject here (thanks again by the way!) The problem is that I have old flashes - a Vivitar 550fd and a Cobra MD210 - without bounce or swivel (they only rotate up and down) so i I'm limited to on-camera flash pointed in the same direction as the lens, I figure I'll need at least a diffuser. I don't actually have the diffuser caps for these flashes, and am wondering what is the best way to improvise? I imagine a small piece of Kleenex or something similar over the flash could work, although it wouldn't be particularly reliable and would probably get ripped to pieces moving around inside the bag. Does anyone know of a better solution for softening the flash? Thanks!
