Hello guys! My question is about high ISO on digital cameras, I was reading some post where others fellows talk about Iso 3200 on a D200 when D200 only goes 1600, I read BOOST 3200 and some very nice photos by the way at that High ISO. On Film you can push or pull trying to get higher or lower result of a film no matter the Iso, is just what you want. Enlighten me please.. Thanks, Marcos.
