Hola!

That is about the extent of my Spanish speaking abilities, but I've become very close friends with some Ecuadorean foreign exchange students. They've both gone out and purchased Rebel XT's ( I think I rubbed off on them a bit lol!), but our language barrier tends to get prohibitive when I start trying to explain the relationship of ISO/aperture/shutter speed.

Can anyone point me to some basic tutorials/primers in Spanish, ideally something like Bryan Peterson's Understanding Exposure?
